Its a cat back for like 134 i saw in JC whitney. Just wondering how it sounds and how it preforms

 

Sounds great, performs better. I'd buy another. It's a quiet muffler compared to most A/M mufflers out there.

 

Yeah very happy with mine... Lasted a long time, performs well, but isn't too loud!

 

I've had mine on for almost a year and 30,000 miles. their right, not real loud but also flows great and no sign of wear at this point.

 

I have heard them on a pair of Z28s before, they seem to perform well, but if you are looking for volume, in my opinion, you are looking in the wrong place.

 

I got it, then saw that they made the 3" muffler inlet by expanding a 2-1/2" pipe. Boo, hiss....

I put a Flowmaster between their I-pipe and tailpipes. A good bit louder than the 2-1/2" GTA take-off I had before, but I can live with it.

 

Aw, really? I have their smaller one right now anyway for the 305, but was planning on getting the 3" for the motor swap. There aren't very many quiet mufflers out there good for 375+ HP.
