I just bought a '95 Trans Am and am looking to replace the stock muffler. Does anyone know what the inlet/outlet diameters are on the stock setup? And, is it 1 in/1 out on one side, and 1 out on the other? Thanks!

 

So ur just looking to replace the stock muffler? Iam pretty sure its 2.5, please someone come in here an correct me if im wrong.

 

Seems like it is an odd ball size, like single 2.75 in and then dual 2 or 2.25 out. I know its not dual 2.5 out as I put true dual 2.5" on and the TA twin tips were a bit smaller than the 2.5" tubing.

Yes, it is 1 out on each side of the muff.

 

If your looking for a replacement exhaust I have a almost new y pipe and catylitic converter ready to go, selling becuase I just bought LT's and eliminated the cat. Let me know, i'll sell it cheap.

what 2quik6 said, its an oddball size. i woudlnt worry about the exact dimensions, just find a muffler thats advitised for the f bodys. the only ones i can think of off the top of my head are the hooker areo and the flowmaster 80 but there are others

 

Hooker makes an aerochamber that's a direct bolt-on. I put it on mine, and I love it.

 

hairbear..do you have a part number on the muffler? I would like to put one on mine for more of an aggressive tone. There are two mufflers for the LT1 application. One is a 3" inlet and the other is a 2.5" inlet. Thanks!

 

Here's the same muffler that I ordered from Summit. The price has gone up though

It's the HOK-21721HKR

My tailpipes were welded on from the factory, so I just ordered some new ones from RockAuto. After doing that, I would just have some bent by someone, or there are places that sell the pipes with mandrel bends.

 

check ur local exhaust shops.
I know i have one here that sells hooker stuff, u might be able to get them to throw in tips with the muffler for the price that summit has their muffler
