92 GT 5.0 - Exhaust suggestions

Tavis · Nov 24, 2021

My wife has a 92 GT 5.0 convertible - all stock. Automatic trans. She has been wanting a better sounding exhaust on hers, and is somewhat jealous of mine (93 GT 5.0 - straight pipes with flows).

I have noticed some rust holes right where the pipe bends up behind the muffler. So I feel like it's time to replace them.
I am in NC and I do NOT have to get this car inspected next year, or anymore. So I'm considering good options to get her a better sounding exhaust. I am looking for suggestions here.

I don't know if I would want to replace the headers yet, but would like some suggestions to get this one sounding better for her.

All stock? Just install a cat-back of your choice and call it a day. I wouldn’t bother with headers at this point unless yours are rusting off the car and have holes.

When I was stock, I had stock H-pipe and flowmaster american Thunder cat-back. Was plenty loud and I loved the rumble.

I have an all stock 91 LX and replaced the exaust system with BBK headers (my orig ones were rusted), an X pipe, and a cat back stainless flowmaster series 44 system and are happy with the loud rumble it provides.

That h-pipe won’t work without long tube headers.

Cat-back is what I have, although an older version that came with super 40s instead. I run this X-pipe now, and it’s loud.

In my opinion you can’t go wrong with a Flowmaster cat-back system regardless of what series. Whatever you choose you will be happy. I think they all sound great on a Fox especially the 40s which is the original Old school ionic sound of a 5.0 and the 44s are very similar. All great choices.
My X-pipe is off road, no cats, and is loud and compliments the flowmasters. Either way with or without cats you can’t go wrong in my opinion. New H/X pipe with a new flowmaster cat-back it’s going to sound great with that deep rumble. Can’t go wrong as long as everything fits like 5L5 pointed out. Do your research on that for sure so there are no surprises or expensive mistakes.

American Thunder with X pipes. I wish I had joined this forum before I got my car because the first thing I did was get rid of the cats. Now I have a small amount of exhaust smell. If I had to do it again I would have kept the cats like was suggested here.

you will gain nothing by swapping shorty headers on an all stock engine. As Mike said, pick a catback system and be done with it.

OK, so you would not replace the cats with an H pipe or X pipe?

nope

On a stock, convertible that would likely be used for cruising around? Nope.

Cat-back and be done.

Your car though, so ultimately it’s your decision and not ours

I think that’s the same as what you listed before.

This is American Thunder with Bassani catted X-pipe. I do have JBA shorty headers but they really don’t affect sound as much. Of course, car isn’t stock. Has heads and cam and other junk.

Since you asked for opinions....mine is they all sound much better with an off road H/X of your choice, if emissions are not an issue.

I'm running flowtech 1-3/4" shorties ceramic coated, a BBK off road H pipe and a 3" magnaflow competition series stainless steel exhaust. It sounds great. But this car is not a daily driver and seems maybe 500 miles or so per year. So this isn't a one size fits all equation.

If this was my daily driver I'd be running cats. The smell doesn't bother me personally, but everyone is different. Good luck with your decision.

Tavis · Nov 25, 2021

I think I am going to go with this one and leave it at that.

Good choice

91AOD5.0LX · Nov 25, 2021

Yes, nice choice! I have the same for the LX (polished tips) and it sounds deep and mean. Your going to like it. Can’t go wrong!

Potomus Pete · Nov 25, 2021

If you like mean, and loud that's it. I have the same, and the price has gone up.

Sure has as did the cost of mine because I waited 6 months before I ordered it. Just like many other things these days unfortunately.
