Within a few weeks I'll have everything done to my 88 XR7 that I plan to do except for the exhaust. I wouldn't touch it but both lers have holes in them so since I have to replace them anyway I might be willing to spend a little more while I'm at it if I get the bang for the buck. I doubt if I'll ever do a mass air conversion, change the heads or fuel injectors but you never know, I might get bored next winter. Assuming that I don't plan on doing anything else, is it worth going to something like Magnaflow lers on stock pipes or upgrading to larger pipes from the Y back? Or to make it simple if I planned to spend something like $300-$400, what would be the best bang for the buck? Would I notice the difference over just going to my local ler shop and getting standard lers installed or is it a waste of money on my stock 5.0?
On a side note I went through the original owners paperwork and the car has is on it's 3 set of lers. Both of the replacement lers were listed as lifetime guarantee but they charged her parts and labor at the same shop when the last set were installed.

Hey Charlie...a lot of guys are grabbing the Mustang 5.0 stock shorty headers, and from there an aftermarket X or H pipe (I went with a catless BBK X pipe, in 2.5") and whatever cat-back kit you want. Keep in mind though, that while pretty much every X and H pipe for a Fox Stang will work great, the rest of the exhaust for the Fox Stang will need lengthened a few inches to fit our Birds/Cats, due to the longer wheelbase.
Now for the rest of the system I went with Flowmaster American Thunder, again in 2.5". I got mine for a '87-93 Stang LX 5.0, but you can also use the GT kits, as the tails are a little different because the GT Stangs had the effects, so the tails come out a bit different.
Any good exhaust shop would be able to lengthen the pipes for you, but if you live in a smog area, you'll need to stay with a catted X/H pipe, instead of the offroad version. Obviously the catted part is a heck of a lot more....if you're only looking for lers, but don't know what to get, there's tons of vids on you tube of different exhaust setups. Myself, I decided on flowmasters because of cost, and that's what a friend has on his '95 5.0 Stang, and I think his sounds awesome. Throaty, decent tone at idle, and it doesn't scream like a glasspack when you lay into it. Magnaflow is pretty nice too, but a bit costly, and a little louder.
Thunderjet302 has a nice exhaust on his car, but of course he has a nicely cammed engine, so that affects the idle and the volume a good bit.

I live in the mountains of Colorado. Denver does emission checks but this isn't an issue where I live so being within emission guidelines wouldn't matter to me. I guess I could technically get away without running a cat. I don't think I want to get into change the exhaust manifolds to header though, I'd be getting out of the budget I'm wanting to hold to. I could get the lers replaced for less then $200, I'm just wondering if it would be worth going to better lers and larger pipes or if I'd be wasting my money.

I'd put some aftermarket Mustang headers (at least 1&5/8" primaries), 2.5" H-pipe (catless if you can), and 2.5" midpipes, lers and tails. It will be big enough that if you do any engine upgrades you won't have to upgrade the exhaust.

Id buy any Mustang shorty header you can find, plenty of used ones out there when guys go long tube. Id rather have a used BBK than new chinese ebay, etc. Probably no more than $100.
Any fox stang H/X, same thing on used, I bought a new looking bassani x for $100.
I used a GT fox Ultra Flo cat back. Snagged junkyard hangers to go dual. Exhaust shop hung the cat back for me with some universal hangers on the tailpipes.

I know you're knowledgeable on this. I'm really looking at the cat right now or headers, something like that could always come later. I'm just looking at the fact that I have to replace my lers anyway so I'd like to make the best choice. If it were worth it I'd go as far as putting better lers and possibly larger pipes from the Y back. Would I gain anything from this or would this be a waste of money over going with standard lers? Would anyone have a really good ler that they would recommend on a budget?

If he's on a budget an offroad H-pipe is cheaper than a catted H-pipe. At that power level I don't think he'll notice much of a difference.

Mine has magnaflows after the Y and it runs and sounds very nice. I was glad to find the PO added these. I will add stock or FMS mustang headers and a mustang stock H-pipe for mine, and the engine will stay basically stock.

Don't ever use chambered lers. Run straight through lers like borla, magnaflow or Dynomax ultra flow. Tom's right about cats, but if your budget doesn't have it, it doesn't have it. You probably won't notice the difference at your level. I know it's sort of like picking a fight with Tom to say so, but he's wrong about lers vs. no lers. Straight pipes on a 5.0L will make less power than straight through lers, there is much data to support this, even on this very forum, dig deep in the engine section, you'll find it. You can Google for things like ler shootout, where in addition to comparing lers to one another, they almost always baseline with none at all. Having said that, I'm unaware of how it affects a 2.3 turbo, so he could very well be right on TC's. I just don't know.

This is basically what I was thinking of for now. I've done a lot to the car this winter and didn't really plan to get into the exhaust this year, however when I discovered the condition of the lers while working under the car I have to at least address that. I currently have stock pipes that are duel exhaust coming from the Y and the pipes are solid. My thought is always if I have to replace something I might as well do it right for the long term. I may or may not get into upgrading the rest of the exhaust from the Y to the heads but it would at least wait until next winter. If I added these lers with 3 inch pipes from the cat or Y back, would I have any hp gain now without doing anything else? http://m.summitracing.com/parts/mpe-11229
I could do this within the budget that I'm looking at, or perhaps someone could suggest a better option.

After speaking with the exhaust shop I'd be using it sounds like 3 inch would be overkill and harder to work with under the cougar. He though 2 1/2 inch would be better. There are a ton to choose from if I want to go that way and the price for that sized magnaflow through the shop isn't much more then ordering them online and have them installed. I found this one but I'm still researching. http://m.summitracing.com/parts/mpe-11226 Any specific suggestion would be appreciated.
And again, does anyone know if I'd see any gain by going 2 1/2 in pipes from the Y back to the 2 1/2 inch Magnaflows while doing nothing else?
If so I'd think anything on this stock 5.0 would be noticed.
The guy at the shop seemed to suggest flowmasters over magnaflows. I told him I wanted to get something a little throatier then what I had but still wanted to be able to have a normal conversation or enjoy my music. He thought the flowmasters would come closer to that.
Abird, how do you feel about how loud your magnaflows are?

If you want lers and bigger tails to do anything for you, you'll need bigger pipes BEFORE the lers, too. Matter of fact, you'll want to go bigger all the way to the engine. Solution: 1 5/8 shorty headers, 2.5" H or X Pipe (neither has an implicit advantage over the other), 2.5" intermediate pipes, and THEN 2.5" lers and tails. Not simply a loud exhaust like all the posers and billy-bobs, but a performance exhaust.

Tom, are you talking new high flow cats or just cats in general? I have yet see a dyno where cats vs no cats makes more power. Mind you I have never tried any performance cats, so I can't really comment there, the guy at the dyno told me a good quality high flow cat will make as much power as straight piping, but to be honest, I like the SOUND of straight piped flow through lers. From my experience removing a stock cat gains 18-20ish hp, now if this is because it was plugged or an oem unit I don't know. My skyline gained 50ish hp when I straight piped a 3.5 inch exhaust from turbo back on it, it really made the car a total animal, same with the turbo cougar, it made spool up way quicker and pulled noticably harder I can't say hp cause I never dynoed it with straight pipe. And yeah you are totally right about exhaust sizing, I have had experience with my N/A 347 stroker, went from no x pipe 3 inch exhaust to 2.5 with x pipe, HUGE DIFFERENCE!

But that's just it, he hasn't got a dual exhaust. He's got a single exhaust, at least effectively. 88 5.0 cars have a 2" y-pipe, and then another y-pipe in reverse, so that even though there are 2 lers and 2 tails, at one point it's just 1 2" pipe between the front Y and the back Y. Most of the restriction he has to worry about is right at the joining of the front Y-pipe.
Maybe a 2.5" inch H-pipe system is too big for a stock 5.0SO, but once he's fitted exhaust, you know he won't stop there, nobody ever does. A 2.5" system will be a system he only has to buy once and he can grow into. Otherwise get a 2.25" system made up of extended stock Mustang pipes. I'm telling you, though, nobody ever stops modding once they start.

It sounds like the consensus is that I'd have no gain in hp by going 2.5 inch from the cat back and going to the Magnaflow would only give me a louder exhaust. This makes sense and it's why asked the question in my first post. Whereever my narrowest point or greatest restriction is would determine how much flow I could get and this would be at the Y. I don't think I'd want to go with just the cat and no lers, I'm afraid that would be too loud.
I thought the Y was greater then 2 inch but if that's the case what if I cut the Y and extended straight true dual all the way back? I guess I'd either have to go without the cat or add 2 new cats to do this. Going without the cat might keep me within the budget I want, adding 2 cats along with the 2 new lers and pipes would likely put me over $500. I'll run this idea by the exhaust shop guy though.
Would I see a gain from this????

You will LOSE with a true dual exhaust! When I first bought the cougar the exhaust was rotten and blowing on the gas tank, so I hacksawed it off just behind the cat. It was a noticeable gain cutting off the rotten exhaust and it wasn't very loud at all. Then I decided to go true dual exhaust with side pipes and cherry bombs, well that dropped the power so much I took it off after a week. I can say an x pipe or h pipe is really needed on the 5.0 engines for equalizing exhaust pressure, a constant feed of flow works better than starting and stopping the exhaust pulses having each sides flow disrupted waiting for the other side's cylinders to fire (at least that is the way I think of it). It is easier to maintain motion or flow than it is to start and stop it. You are not going to notice the difference by seat of the pants from 2.25" to 2.5" cat back exhaust. Plus I like the SOUND of the larger exhaust better, plus you can grow into it.
You can go with 2 cats INSTEAD of lers!! That might be something to think of, you are emissions legal and make more power than most lers! That is something I might try I am really curious now!

What about a larger pipe at the Y along with a single larger Cat so the intersection didn't restrict so much. Then go with larger pipes and lers. That would be less expensive and less labor then changing to and H pipe and I'd only be out 1 cat instead of 2.

Just find a Mustang guy throwing out a stock H-pipe and stock headers, then buy some intermediate pipes for a Mark VII. Even the Mark VII stock H-pipe (smaller than Mustang) would be better than trying to fab a better double Y-pipe. The Mark VII pipe is probably harder to find. The intermediate pipes are dirt cheap and Mustang guys practically GIVE away their stock headers.

Tom,
It wasn't simply cutting off the cat, I did 3' downpipe which eliminated 2 precats, removed the cat, ler and resonater. I went to 3.5 mandrel bent exhaust all the way to 4 inches for the last 2 feet. The cats were so plugged the boost was only hitting 12psi with the boost restrictor removed. The boost went to 18psi after. It was a substantial improvment, same with the cougar, the turbo t/a, and the grand national ALL GAINED quite noticeably from straight piping. I do agree with you, as my n/a 347 made most power through the x-pipe exhaust, more power than straight headers AND true dual 3'exhaust. I will be trying an xpipe 3' exhaust with 2 high flow cats instead of lers on the cougar when the motor goes back in it this spring.
PS: Keep in mind I am no mechanic, no tuner, just some redneck hick who does stupid stuff to cars that blow them up all the time. I can only
say from personal experiences.

Not too far off topic but what about coatings versus wraps? Let's ignore the cost difference and just look at performance differences. Would there be any benefit to wrapping or coating just certain components of the system or if money was no object would you want to wrap/coat the entire system?

Sorry for the confusion there, I brought turbo cars into this when we were talkin stock 5.0 setups. I was refering to my nissan skyline it gained huge results from removing all the that was in the exhaust path. I put 3 inch mandrel bent exhaust on all my turbo cars. The different piping is just cause that is what I had laying around for the skyline.
On my 347 stroker naturally aspirated tbird I insisted on 3 inch dual exhaust with no h or x pipe, the guy building the engine argued with me. I was a little disappointed at the drags, so he talked me into an xpipe setup with dual 2.5 piping, man big difference!
so now my next question is do supercharged cars still need the x pipe, turbo cars merge the exhaust before the turbo so that is taken care of but what a blower car?
My buddy is putting a 6-71 on a stroked 5.0 and he was wondering about the exhaust setup on that.
He was thinking long tube bbk headers, then just running lers with side pipes exiting in front of rear tires. Is the x pipe needed on this application? Some guys say yes some are saying no, but I'd like to know from someone who ACTUALLY HAS a blower on their ride.

Order replacement tailpipes for a 5.0 lx mustang from a parts store. Get two lers of your choice, and some stock stang shorties with a mark 7 h-pipe. It should all bolt together and cost less then your $400 if you do the work yourself. The mark7 h-pipe has hols near the header so you don't need to legnthen any wires or move the o2's.
I ordered a 4 banger mustang tailpipe for my thunderbird for $60, the cat to ler pipe for $40, and threw on a $20 cherry bomb. I was into it cat back for $150, and it fit like stock.

Post 2 has pretty much all the pertinent info...do people not even read? Just see a thread title and suddenly lose 95% of their intelligence quota?
WTF.
Then we have talk about exhaust pipe size on a turbo car...opinions are rampant, with no factual info posted for proof.
If you can't answer someone's question accurately, succinctly, and with factual info, GTFO.

You do realize the mustang tail pipes are to SHORT for a T BIRD or Cougar. A lot shorter !!!!! You have to make them longer to work correctly

Have you ever used mustang pipes on a T BIRD OR COUGAR STACKS. They are to SHORT. Well what can i say!!!
:mullet::toilet::rollin:
Ever try to order a tail pipe for a cougar/tbird?
When my buddy bought this car, an exhaust shop wanted $400 to fix the exhaust. After pricing it out on the tail pipe, we decided it would be much ceaper to get inventive with the mustang tail pipe. Now here's the funny bit, using the old cheap glasspack looking ler, the offset was a bit off, but the tailpip was the perfect length and bolted right to the existing cat. After it was put together, he had an exhaust shop weld the clamps so it wouldn't come off or leak again.
The mustang tailpipes are the perfect length, its the midpipes that are too short. You can see this in the wheel base differance between cars. Running the longer "turbo" ler made up for the extra room.

I've got to go with Tom on this one. The Mustang mid-pipes ARE shorter by about 4 inches, but the tails are shorter by about 8. For guys that want to hide their tails, this is usually either extended a small amount or left alone as GT tails, like 4 cylinder tails, have a turndown at the end. Guys who want a visible exit usually use LX tails (straight exit and lower mounting) and put long tips on to get the right length. This is an established fact on this board, and I personally have done many of these during my years in undercar shops. I'm not saying it won't work, but it don't look right. The exit would end up halfway between the wheel and the bumper.

My turn down is about 2" short of the bumper. The mustang hangar even lined up with the exsisting tbird tail pipe mount, although it was a different style.
I'm not arguing, I'm just saying what I have done.
Went down to autozone, ordered a mustang tail and mid-pipe, hooked it up. It was my buddies car at the time, and he didn't want to have to wait for an offset ler, so we used a cherry bomb.

I wonder if the replacement I ordered was cut to fit? This would give some length in the mid-pipe area.
The hump in my tail pipe is in about the right place, and it was not extended. Maybe I'll call my buddy up and see if h remembers ordering it for a mustang. I'm 95% sure that's what we did.

Hey Charlie...a lot of guys are grabbing the Mustang 5.0 stock shorty headers, and from there an aftermarket X or H pipe (I went with a catless BBK X pipe, in 2.5") and whatever cat-back kit you want. Keep in mind though, that while pretty much every X and H pipe for a Fox Stang will work great, the rest of the exhaust for the Fox Stang will need lengthened a few inches to fit our Birds/Cats, due to the longer wheelbase.
Now for the rest of the system I went with Flowmaster American Thunder, again in 2.5". I got mine for a '87-93 Stang LX 5.0, but you can also use the GT kits, as the tails are a little different because the GT Stangs had the effects, so the tails come out a bit different.
Any good exhaust shop would be able to lengthen the pipes for you, but if you live in a smog area, you'll need to stay with a catted X/H pipe, instead of the offroad version. Obviously the catted part is a heck of a lot more....if you're only looking for lers, but don't know what to get, there's tons of vids on you tube of different exhaust setups. Myself, I decided on flowmasters because of cost, and that's what a friend has on his '95 5.0 Stang, and I think his sounds awesome. Throaty, decent tone at idle, and it doesn't scream like a glasspack when you lay into it. Magnaflow is pretty nice too, but a bit costly, and a little louder.
Thunderjet302 has a nice exhaust on his car, but of course he has a nicely cammed engine, so that affects the idle and the volume a good bit.
This really does look like the least expensive way to go to really make a difference. If I were to do it myself I could possibly pull it off within the budget I've set but I really doubt if I'll have the time but we'll see. I'm in the middle of 2 projects on the car right now and I have to start some very time consuming home projects after that which will take a few weeks. At the very least I think I'm going to go with the 2.5 in lers that I want and put off the rest until next winter when I have more time, I've propably spent 150-200 man hours on the car this winter now just on a lot of little things really. I was hoping to get some gain without getting into too much work but I'll at least try to move in the right direction for the long term.
Since my old cat is the OEM and Tom suggest that it is restricting, do you think I'd have any gain by eliminating the cat in my current system in the short term?
I guess I'll start checking craigslist for the headers in the near future. Any suggestions on where to find the X pipe?
Thanks: Charlie

I run 1 3/4 long tubes and a 3" h to 2 chambers to dumps on my 5.0 lol lets stir up the pot some more lmfao
It's over kill but it's a track only car lol
I'm on a budget with the TC and for now will most Likly just run a strate pipe off the cat and ditch the dual tails

I'll try to revive this in hopes of some simple advice before deciding how to proceed. It looks like 302's suggestion of going with used mustang headers is sound. I found some locally for $35. Does anyone know how restictive the oem exhaust manifolds are as compared to the 1 5/8 shorty mustang headers?
Finding a used x pipe doesn't seem so easy, any suggestions on where to search for this?
Tom suggested that 2" pipes where enough for up to 200 hp.
Foe suggested that my biggest restricted area was at the Y going to a single 2" point followed by my factory cat which creating further restriction.
What if I had the Y cut off and added a short X pipe like this one for $40, then went with my dual 2" to a better ler?
Should I not see some gain from this?
I found an exhaust guy willing to do the work on the side with our without a cat and since i don't have a lift or torch I really hate to tackle this myself.
Tom I know you're against eliminating a cat but you suggest my factory cat is restrictive. Would I see any gain by eliminating the cat and doing without?
Does anyone with knowledge of this know what gain I might get going with the headers to 2 1/4 or 2 1/2 x pipe and high flows but did nothing with the heads or engine?
It sounds like the factory exhaust is really restricting things with my stock 5.0 putting out 165hp. Would I see 20+ hp gain?
Any idea what I might gain by staying with 2 inch pipe but eliminating the bottleneck at the Y?

The stock cats are restrictive that is a given. So i am going to say with a dual setup with the x you posted and say a 2" exhaust all the way back with stock manifolds . I would suspect 8-10 HP . That is from experience. The shorty headers dont really do much but better than the cast iron ones. I would suspect a set of shorties will increase your HP by maybe 2 HP over the stock setup. just a guess in my opinion. Figure on app 12-13HP with shorties and a 2" full dual exhaust past the rear axle.. Good luck!!
Thanks, this is very helpful. Would a 2 1/2 X off the headers then 2 1/2 all the way back make a difference over 2" without doing anything to the engine?

I thought I'd have to find something local to make if worthwhile with shipping. I tried all the local craigslist areas and the colorado mustang forum. No luck so far.
I did find a 2 1/2 in H pipe but from reading the thread I thought finding an X pipe would be better. Your thoughts?
I haven't really decided which way to go yet and I'm still searching, new stuff is posted everyday. Any suggestions are appreciated.
If there's an advantage in going with 2 1/2 over 2" all the way back then I'm still considering that. If not, then it's a great deal of work taking off 25 year old exhaust bolts in the manifold and changing everything all the way back versus cutting the Y and inserting the aftermarket X pipe and staying 2".
BTW does it matter what year Mustang the X or H pipe is from as to how it fits under my fox cougar?

There's so much stock stuff you can run for cheap. 87-93 is what you'll be looking for. Mustang stock headers, 2 1/4 Mustang stock H, extended Mustang stock pipes and tails with some Mustang Magnaflows. You'll want to look for an H from a car with AOD to get the best fit. The lers will probably cost more than the whole rest of the system if you buy take-offs from Mustang guys on boards and swap meets. $500, tops all together and you don't have to worry about whether not having cats will hurt you. I'd estimate 15HP, which seems low, but that intake you're running and those heads and cam would be what's holding you back (in that order). With an Explorer top end and an HO cam, your exhaust gains would be higher (I'd guess at least 25HP), but the E6 heads, non-HO intake and cam make it wheezy and all the exhaust in the world won't make it suck more air in than the top of the engine can flow. Like Tom is fond of saying she's an air pump.
Aside from that, I wouldn't waste time looking for an X, because until you're running high rpms and much more power, you're better off with a cheap and highly available H. Spend less on an H instead of an X and be able to spend more on everything else.
If you're looking for power and you're only thinking about the exhaust, you're wasting your time. And if THAT's the case, just go for a good sound. Guys on the street won't know the difference.

Thanks, good info. I thought I might need to look into fox era mustangs but I wasn't certain. The H I found was off a 98 so that wouldn't work. I guess I should bring up that giving up any clearance isn't a good idea living in the area that I do.
As I said in my first post, I have some exhaust issues so my thoughts are since I need to do something why not try to add a few hp if I can do so within a reasonable price. I'm certainly not getting into the heads or intake this year although I did have the intake off a few weeks ago to be able to change the valve cover gaskets. Like anything I'll way the pros and cons and make a good informed decision.

I called my buddy back home who has done 100's of these exhausts on Mustangs at his exhaust shop and he said that the full exhaust system off a 94-95 Mustang will work as well. Just another source if you are having a hard time locating Fox stuff. The headers and H-pipe from a 96+ car will not work due to the 4.6L motor but the cat back might but I did not ask him about that. To answer that you could check Summit and see if the cat back is the same for the 94-95 and 96+ cars. If you are not in a bind and have to have the exhaust now then definitely shop around. For me finding the stock 2-1/4" cat back stuff would be next to impossible as they have all been ditched for 2-1/2" stuff long ago around here. The trick is to find someone who has pulled their cat back or at least the tail pipes off in favor of dumps. Alot of guys would keep the stock shorties and H-Pipe and just bolt up a 2-1/2" cat back. I think that is where you are going to find yourself heading and it will be a great exhaust for the money you spend and it will even work really well with a HCI swap.

'87-95 5.0 will have the basic same H or X pipe...after 95 the Stang was of course the 4.6, those used a wider pipe up front to accommodate the wider engine.
I've got a set of stock 5.0 Stang headers...sitting here collecting dust. For that matter, if you plan to have a stronger engine later on, may as well toss on a set of good aftermarket headers...BBK1515 come to mind, and not only will they bolt to So or HO heads, they will also work great with GT40P's as well.
Or you can buy me a set of the 151's, and I'll send you my 1-5/8" Flowtech's..they won't work on P heads, but they fit great on everything else. :D

Thanks for going to the trouble of checking on this. If I could find a complete setup off a mustang locally at the right price I think I'd have to do it. Time is really on my side since I don't have to do anything this year. I could just drive the car this summer with the hole in my ler. I live in a tough area to find anything. It's a very high cost of living area with no junk yards or exhaust shops within several counties. The nearest exhaust shop is 75 miles away near Denver. Getting anything worked on here is horrible, I stopped by a truck shop today to see if they'd be willing to install the X pipe if I brought it in. Sure at $138 per hour.
I think my best bet is to keep checking Craigslist around Denver and see what comes up. I could pick something up and take it to an exhaust shop down there in the same day.
302 I appreciate the offer but I think with shipping I'd be better off finding something locally. I found 2 sets of headers now on Craigslist, one for $35 and one for $50.
I didn't ask but would I be giving up any clearance with the x or h? Roads here in the mountains are very kind to low clearance.

No more than a conventional exhaust. Unless your car is lowered then it will be fine with regards to clearance. One thing I did think of is that you will most likely play hell trying to find a stock H-Pipe with cats in the Denver area as most keep them to pass emissions and then throw on the off road pipes.
Just stay patient and even if you have to drive a couple hundred miles round trip the cost savings will be well worth it.

I found a cat back setup in the Denver area. It's an aftermarket flowmaster cat back with that came off a 94 mustang. 2 1/2 inch wtih H pipe high flow cats and lers. It doesn't include the headers but the price is right and from what I'm reading here it sounds like 94 would still fit with some minor pipe extensions to the manifolds or headers if I buy those. I'm going to look at these this Sunday. Let me know if this is a bad move before I pull the trigger on it but I think I'm going for it if it looks as good as the guy says. He said the setup only had about 10k on it.

10k on flowmasters is going to mean "rotted out", probably still worth a look, though. You MAY have to extend the pipes between the h-pipe and lers, and you MAY have to make the tails longer, but you can add chrome extensions easily. You'll want aftermarket headers, because in addition to having too small of an outlet to fit the h-pipe, your manifolds will have too narrow of a spread between the studs, ask me how I know. Even the stock HO headers I was running on my engine were too small to fit my 2.5" h-pipe s.

That's good to know since the headers I was thinking about getting were stock shorty headers. I did see a set of Mac headers on craigslist, I don't know if they would work though.
I can't believe the lers would be shot with 10,000 miles. I get 200,000 out of a new stock ler. Do they make these flowmasters that poorly?

If it's never seen salt, you're probably ok. Otherwise, they're made of aluminized mild steel, so with heat and salt put together, they tend to have a limited lifespan.

Either way lers are cheap. It's all the pipe and mandrel bends that cost the money. DO NOT get the MAC shorties, cannot say enough on how shiznitty they are for fitment at the heads.

We had a little too much snow to check out the exhaust in Denver this week. I may check it out next week but I saw another listed today. It was taken of a 2013 mustang with the new 302 boss. I don't know anything about the changes they made when reintroducing the 302 but it's the complete system, I guess the guy just upgraded his entire exhaust. Anyone know if this would bolt up?

Not in a hundred thousand years. Sorry. Like the rest of the car, the engine is 100 percent different, throttle body to the drain plug. The only thing in common is suck, squish, bang, blow.

If it wasn't cost prohibitive, I'd send you the 2" H and stock HO headers I just finished with.

The 5.0 Coyote motor is a modular motor and entirely different block than the Windsor family. Stick with the one you found earlier as it will be your best bet with it being 2-1/2" there is room to grow.

Thanks for the info. It's a shame though, the guy just bought the car and took it home to start working on it. He said the exhaust has around 30 on it. I'll keep looking and may go for the Flowmaster set up.

Can't argue with Tom's logic. Glad he finally admitted that 25yo cats are bad news. Old lers can be just as bad. Flowmasters have the best sound of all lers in my opinion. I must warn you though, sometimes they will cause a terrible drone sound at highway speed. I have suggested in the past to use a good set of turbo lers. They have no drone sound and are cheaper than anything else other than glasspacks. I have caught hell in the past for such a suggestion, but I do believe they do well in flow and have a little performance sound without being obnoxious. As for the manifolds, they don't have leak problems like some of the headers do, or clearance problems either. Yes, they are a restriction, but they are trouble free. I honestly don't think the restriction from them cause a hole lot of problem if the system behind them is free flowing enough.
OK guys, I am ready for my post to be bashed. Let me have it.

I won't bash you, I'll agree with you, but I have to point out that trouble free as manifolds may be, they do outlet at 2" and do have too narrow of a to fit anything except their original y-pipe. I'm running Dynomax super turbo's myself, and at his level the same setup wouldn't hurt him, although my next step will be Dynomax VT. Straight through, but with a spring loaded valve to cut out drone. I hear good things about them.

I'm gonna have to agree with Chrome too but like Foe said the manifolds have to go. At a minimum stock shorty headers should be installed to take advantage of the better exhaust. I have seen many sets of used unequal length shorties online for $100 or less but I would stay away from the MAC's (personal preference). I have a thread on cleaning up the aftermarket shorty headers on a motor I built for my Coupe on here if you want to check out what I did, go to page 3, post #22. I only bring this up as the outlets on most shorty headers are not 2.5" with the exception of the JBA's which are the closest.

I missed out on the aftermarket exhaust, I just couldn't get there in time with the snow storms we've had on my days off. It seems almost impossible to find everything off a stock mustang in one purchase which is what I've tried to do. I think I'm going to look into finding what I need in multiple purchases which may cost just a little more. I came across a stock H pipe from an 89 mustang GT. It has the cats on it, does anyone know if these would be high flow or too restrictive for what I want to achieve?

You can bet that they ARE a restriction, but with your setup you're still going to gain over your cast manifolds and Y-Pipe. The engine is an air pump, but yours can't pump enough air for it to matter. You're on the right track, so keep going.

If you do not have emissions testing then just hollow them out with a long screw driver or pry bar. This used to be the trick back in the day when not much else was available. This is of course for "off road" purposes only...

I thought about doing something like that but I'm afraid the exhaust shop would refuse to install it. I don't have emissions test but there are no exhaust shops here so I'd have to go to Denver to have anything done where they do require test.

It may come down to me doing it myself but I really don't want to. I've rebuilt engines in my youth and I think I'd rather change the heads and intake then deal with the exhaust.

Basically from the headers back to the lers it will just bolt in the car. You will need one of the ler hanger brackets for the rear and obviously this would be the side that the car currently does not have a ler on or if it already has factory duals (did any of the Birds?) then you are good to go. From there take it to an exhaust shop and have them hang the tail pipes and put some nice chrome tips on the ends to extend them to the correct length. You can use the Mustang GT tail pipes and have them lengthened with a same diameter piece of pipe and reuse the turn downs at the rear bumper. This should keep the exhaust pretty much concealed like the Turbo Coupes.

I thought I'd put the update here since everyone has been so helpful on this. I was ready to pick up headers from 1 source and the h pipe from another when I guy called about the ad I've had running for several weeks as wtb.
He has 21 old mustangs and parts for anything I'd think you could want and he's starting to clear some things out. I'm buying his 2 1/2" BBK X pipe, shorty headers and a flowmaster cat back a week from today. He agreed to put everything on for me within what I want to spend and I'm picking up a 5 speed transmission for a friend with a Mustang while I'm there. I feel pretty good about this direction and it should give me room to grow if I go in that direction.
I'll be eliminating the Cats, should I have any concerns with sensors or do we have any on these?
Thanks again to all for the advice.

We have two O2 sensors just like the Fox Stang. The H or X-pipe will have the holes for them. The O2 sensor harness will need to be lengthened a few inches for the O2 sensors to reach their resting place. They need to remain on the car and functional.
With the cats gone, you'll be fine, your sensors will be fine.
