3” exhaust for trans am
 

Anybody have a 3” exhaust with tailpipes and splitters on a 2nd gen trans am if so what kit ? And pics please

I've got 3 inch exhaust from my headers to a set of Doug's cutouts and to the X pipe. Everything from the X back is 2.5 inch. It clearly isn't a kit.

If you have any kind of performance setup, 3 inch is the way to go.

Number 1 , you do not need 3" Exh back passed the mufflers unless your exceeding 650hp and number 2 , you will give yourself a hell of a hard time to fit 3" tail pipes back there and not having any rattles taking place at times!

Steve I beg to differ. My 2nd gen Torque Tech 3" fit great and no rattles. Unfortunately he retired a year or so ago and no longer makes F or A body pipes.

got a full 3" kit on my 72 from pypes, everything fit great including the 3" tails... & zero "rattles."

Never have heard a complaint from anyone using a Ram Air Restoration system. It ain't cheap, but you get what you pay for, usually.

Complete Torque system on my '70 TA including Dr. Gas 3.5-inch in / 3.0-inch out X-pipe and 3-inch tail pipes. DynoMax 3-inch mufflers.

No issues.

I'd say anything over 550hp will lose power with 2.5 inch exhaust..my car picked up a tenth and a half and 1.5 mph dropping the 2.5 tailpipes.

I believe the OP makes enough power ...

If I didn't just need 3 inch tailpipes I'd order another kit from PYPES.

I disagree. There is plenty of dyno testing out there that shows 3 inch is better than 2.5 for pretty much any power level with these levels of displacement. There is plenty of room for it as well.

Anyone have a pic of the 3” Pypes system installed with the splitters on a T/A ?? I heard the you can’t run the splitters with there setup ...

I have what your talking about I think but can't seem to post it on here I can text the pictures to you if you want send me a pm

Since I have a 9", I doubt I will get 3" tailpipes on it. If I'm wrong, someone please educate me.

.

You can't....also last I checked they discontinued the 3" splitters.

Your wrong....lol

I had the Torque Technologies 3" tail pipes with my 9" and all fit well.

That's good news, but the bad news is they're not made anymore!

Any other tailpipes that work?

I should have a new set of 3 inch tailpipes next week. I informed the shop I'm dealing with there is a big market for these.

I talked to your guy and said I would wait and see how yours fit before I buy a set , are you planing on running the factory splitters ? Somebody said the 3” splitters are made anymore... I have a set that I think got from Pypes years ago but there on a set of 2.5 tailpipes I will have to try and save them ...

3” splitters are available
 

I have a set of 2.5 splitters I may put them on the end...I'm not sure..my car isn't as stockish looking as yours so I'm not that concerned if I use them or not..if I do use them I will open them up a bit more.

A good muffler man should be able to make it fit nicely :-) Too bad there are not that many truly good ones out there. No rattles on mine.

Even though it is overkill, I still documented a nice power gain with full 3" on my very mild 455.
