I have an 06 gt and i cant wait to put the roush extreme performance exhaust on. Silly question being that it is just a cat back; did u feel any power gains what so ever? i have a tune and intake installed and pulleys are going in this friday. Idk if that matters.

Don't expect any gains.

I was told I "should" gain some, due to less restriction, but I don't think I did. If I did, it wasn't noticable and was not the reason I put them on.

I did notice quite a bit of difference with my tune and intake (both from Steeda). I had the exhaust installed first and a few months later installed the tune and CAI.

I've had several comments (all of them positive) about the exhaust. It sounds great at startup and when accelerating. At idle, you can have a conversation without shouting. Deceleration provides a nice gurgle. I can’t recommend these enough.

I see I need to add some more sound clips.

These are muffler deletes, right? Manufacturers and vendors will say you should see a claim with muffler deletes, I'm not buying it. Cat deletes, a minimal gain, mufflers, nahhh. I'm tempted to switch to a muffler delete a/b because I want some more volume while keeping my stock mid pipe though. Maybe next spring.

Depending on power level cat deletes can give decent gains. On yours I would think you're probably looking at about 10-15hp.

No mufflers on these. Just a straight through design.
