I have an 88 Sport.
In the fall of 2K6 my pipes were rotting pretty bad and I didn't want things falling off and damaging the underside. A buddy and I took off the whole exhaust from the cats. I've been driving it like that since and have had no performance problems, or cop stops either. It's loud but not much more than some I hear with decent dual systems. Though a good setup SOUNDS sweeter.
I am delaying putting anything on because I am afraid at 21 years, gettting the manifold off so I can put on the headers + H pipe will be a problem. How do you take out a bolt that has been in place for 21 years and is probably fused solid in the block?
Also am I doing any damage? Should I have anything adjusted (timing, fule mix)?
Runs fine @227000 miles on original engine + trans (AOD) and getting 22-24 MPG highway.

I wouldn't worry about it too much. The bolts should come out fine. I think there a 9/16ths or 5'8ths. You'll need both a deep socket and a regular on for the studs and the farthest back bolts.
Overall, they were kinda tight, but with how big the threads are you should be able to get them off without breaking them.
:rollin:
your speculating. theres no reason why you couldnt test each bolt one at a time to see what you are up against. I wouldnt think any would be a problem unless there is an odd buildup of corrosion.
My way to remove them is to start the car for about 30sec and shut it off. this warms up the metal near the bolts and the heads expand a little. helps break them loose.
Thanks. I knew someone would have reasuring words and helpful info.
I'll post when I get to the point I want to do it.
I have some shorty headers if your looking for a set. PM if interested
I've had a set of headers for about 2 years. Just haven't felt the pressing need to see if it can be done.
I've been thinking I would do it when the engine decides it's time for a overhaul/rebuild. At 227000 miles it may come sooner rather than later.
As long as I am not being harrased for the noise.

when i was swapping the the stock heads off my 85 cougar for a set of 64' 289 heads i just soaked the bolts with a little wd40 and tranny fluid let it sit over night and they came right out
