I have it, it's loud but not overwhelming. Im gonna go LT headers eventually and that'll wake it up. I will say the 5" tips look amazing and get a lot of compliments.

I have the full comp. Cat back and love it! t sounds great but this system also replaces the stock resonator with a baffled "X pipe" or crossover so I wouldn't know about the axle back sound.

if you are going with a system from the "cats" back to the tips I would recommend Corsa. If you are only replacing the stock mufflers (axle back) then go with GMPP. I say this because every other system has horrible drone that makes the car buzz inside and yor ears ring from about 1500 to 2000 rpms...lots of companies claim no-drone but from members posts from other readers, the only ones I've heard don't drone are Corsa and GMPP. I have SLP mufflers and will be doing a modification called a helmholtz J-pipe to get rid of the drone in the near future.

I have the 2.5 Comp Magnaflow cat-back. It sounds pretty good. It is not overly loud and the tips look cool. I have an LS3 and the only thing I don't like too much is how it pops a little on decel. It has a really unique sound and overall am pretty happy with it.

As others have said, it shouldn't be too loud if your running stock headers.

When you add headers anything "straight" is ridiculously loud....I couldnt stand the sound and tone....but with the stock manifolds and cats it sounds great.

I'm jealous of you then...but don't think I'm interested in turning of AFM. Does that make a difference with drone?
