What are people doing for exhaust?

One area of my 82 I'd like to finish is the exhaust. I'm running stock Mustang shorty headers, H Pipe, mid pipes and mufflers. Most of this was given to me, so I can't complain. I never extended the midpipes, so the mufflers are too far forward, and I'd really like some tailpipes. I believe if I extend the mid pipes, everything else should bolt up like a factory system. I've been combing craigslist for the Mustang tailpipes without much luck. Someone's got a brand new complete Flowmaster American thunder catback system posted right now for $250.00. I'm tempted, but not sure if it will fit around the fairmont gas tank. My trunk doesn't have the well for the spare, so I think my gas tank is a little different than the earlier models. I like the sleeper look of the turn down tailpipes instead of the big chrome tips, and this Flowmaster system has those. Has anyone else done a full exhaust swap?

i've heard the stock Fox Mustang exhaust tailpipes are still too far forward, but i haven't seen it for myself. I have the Mustang gas tank in mine, and am not sure what i'm going to do for catbacks either. i would like to get some kind of flowmaster setup like that, but i know i would need something between it and the H-pipe, AND i don't know where the tailpipes will end up. whether they will be too close to the gastank, and too far under the bumper. I had to invent how i hung the gastank, so i don't know if it sits in the same place exactly as it does in a Mustang. Ideally, I'd like tailpipes that sort of hug the very outer edge of the rear overhang like they do on a stock LX 5.0L. I don't know how to do it though.

mustang tailpipes will have to be modified, any muffler shop can do it.

my shit is too loud to be a sleeper like id want, but with that cam i dont think id be fooling anybody. i have big lontubes with a catless hpipe and a pair of dynomax bullets on there dumped way to short lol

I have shortys and an H-pipe, but then it goes 2-into-1 before the 3" muffler, and a 3" single over the axle, and straight out the back, on the driver's side. I would've liked to have an actual merge collector where the muffler is, and a round muffler behind the axle(which is what I asked for), but the guy at the exhaust shop is an idiot, and can't do like he's told.

Maybe next time.

I have a complete mustang exhaust on my 4 door. Stock H pipe with 2.5" flowmaster mufflers and flowtubes, and 2.5" flowmaster tails.

All I had to do was put a 7" spacer in between the mufflers and the tails, and then it needed tips so it would exit the car. I also used the Late model resto tail pipe mounts for a mustang, I just drilled the holes in the rear frame rails.


If you look at the bottom of my cardomain page you will see them. http://www.cardomain.com/ride/2971637


BTW, I've watched the vid of your car doing a burnout on youtube 100's of times lol, it helped me see how much fun my car was gonna be.

I did the same as revolution 909, using stock-diameter pipe for an LX Mustang made by Walker/Dynomax. It all fits and looks great. The tail pipes were extended using stock stainless-steel tips from an LX held on to the tailpipes with stainless-steel band clamps also from Walker/Dynomax. The band clamp bolts also provided a way to suspend the tailpipes via the rear bumper bolts that go through the frame.

Thanks for the info. There used to be a guy on the old board with a green 4 door. I remember he used all stock Mustang exhaust, but he extended the mid pipes (before the mufflers). He claimed that this put the mufflers in position to use the stock hanger locations. Rev, it looks like you used normal mid pipes. did the muffler hangers line up ok? I also know the gas tank changed at some point. I saw your drivers side tailpipe picture, but did the tailpipe on the passenger side clear ok? That's the one im worried about.

I did use normal mid pipes, but I used a clamp on hanger and moved it toward the back a bit from where it was on the muffler so it would line up with the hangers better.

The passenger side fits a bit tighter, I was running 265's and had a bit if trouble with the tailpipe hitting the exhaust, just. I bent a part of the gas take that was causing the tailpipe not to fit right, and then it was fine.

More and more i'm thinking the way to go is to order myself new Flowmaster catbacks unwelded, so i can bolt it right to the stock H-pipe flange, mount the mufflers in the stock location, and then extend the pipe between there. and then extend the tailpipes as needed. Pretty much exactly what some of you guys have done.
