For sound only I strongly prefer the GMMG. $700 though. Is it stainless like the Corsa?

"Best" is relative, but as I see it, the LoudMouth is the lightest cat back, it is one of the cheapest, it's stainless and there isn't much question that nothing out flows it.

For a quiet catback I chose the Hooker for the T/A. It was priced right and sounds good.

I got my borla for 515 from MTI, I love the tunablity, have tried all the plates. Most of the time I just leave the plates out. everyone may say its raspy, but damn i love that nascar sound. Meanest Ls1 i heard was FLP LT's with a borla system. I looked at corsa and GMMG but when it came down to it I just love the borla intercooled tips.

Well you can get the GMMG and put better tips on it. The ones that come with it are really ugly. In my opinion the GMMG sounds better than all of them, and it isn't raspy like the LM either.

Best bang for the buck... take a piece of 3" tube, cut you exhaust just before the 90' curve before the muffler and create a cut-out... should take you 2 hours to do it yourself (What I did)... It pretty much sounds like the loudmouth and most of the flow bypasses the stock muffler.

I have some friends in the area with different exhaust... I prefer the Loudmouth... and mine sounds quite the same... at idle, it's like stock, but then a nice growl follows... I don't find it too loud... just good.

Before I get bashed, note that opinons vary dramatically on these subjects due to different tastes and tolerance levels of noise/pitch... so chose one that you love the sound.

I did this because 1 guy from my area did it and the sound was great... so for the $$$, it's the cheapest you can get.
