In my experience, most every single Bird/Cat from 1983 to 1988 had a double hump.  Plus an '88 5.0 car should have factory "duals" anyway.  In other words, you can just stick an H-pipe directly in where the factory 2-1-2 Y-pipe is.  Only other thing that needs to change is Manifolds-->Headers.

Well they "sorta" had factory duals.  I have seen some that had the double hump and some that didn't, just have to check. :dunno:

It's probably whichever one they had on hand at the time got put on, especially '88, being as there was a totally different car in '89.  :dunno:  :grinno:

hmmm, well i wouldn't know what the hell to look for, but this is how my exhaust is currently set up, 2 pre cats, the pre cat on the right runs into the precat on the left, and from the precat on the left 1 pipe comes out and back into a ler mounted midway of the car and then 1 straight pipe all the way back, so its in no way dualed back, its super restrictive, let me know thanks



ok i just saw that pic that was posted, yes, mine is almost like that but no dual pipes, it's just a single after the 3rd cat, goes into a ler, and then a single out all teh way back, but the guys is selling an h-pipe off a fox body stang, and he needs to know if it's a single or double crossmember, i could take a pic with my phone and post it a lil later, but i was hoping to pick it up today, if anyone could help thanks

Double or Simple, its the same Cross-member.... The diff is on the Pipe Holder....

I believe there are some slight differences in the crossmembers themselves.  One of my cars did indeed have a single hump crossmember.  Even though the car has single exhaust now, though, it should fit duals fine.  And, even on my '85, when no car had the option for dual exhaust, I had a double bushing thing for the H-pipe.

Yes, on the single hump, the left side is a little flatter than on the double. :)

The H-pipe will fit if you have a floor shifter. If you've got the column shifter you have to do some creative beating with a hammer.

My '85 V6 T-Bird had the single hump member. My 88 5.0 Cougar, 87 Sport and 88 5.0 'Bird all had the double.

I had some interference with the rear s and the underbody. Makes it hang down a little farther than I'd like ( speedbumps).
Also had to bend the mounting "horn" a bit to get it to slide into the rubber bushing.
Then there's lengthening the O2 wires, bending the motor mount tab for header clearance, changing the smog pump's air injection tubing, new header bolts, modifiying the column linkage, and so on and so on..... (http://www3.telus.net/neat/icons/blah.gif)

yeah but hopefully the exhaust shop i take it to can do it

i checked and it was a double hump, the hump on the right seemed to be a lil higher but there was indeed two humps, so :D so looks like it's time to just slap on the stang headers and do the exhaust :)

The double hump in my TC, came from my '87 Tbird Sport parts car....
