Aftermarket exhaust? That's as to be expected. Put a smaller exhaust tip on ;-)

Im using the UUC exhaust (www.uucmotorwerks.com) it sounds GREAT and it preformes well

I've heard stories about APR's exhuast also being quite the kick *** piece of exhaust technology (www.goapr.com) Never heard the sound of it but it's very aggressive from what i've been told. Also it's been said that it's louder.......which is still hard to measure unless BOTH exhausts are brand spankin new and tested at the same time......anyway

MTM's is super quiet, and looks beautiful. My buddy just got his in the mail today and i probably can't wait until he installs it more than he can't. It's the most expensive one out there......

Either way, turbo spool will be faster, your car will feel faster and you'll be a happy camper.

lots of popping and gurgling when you downshift. Great for racing around, not good for commuting. If anyone in the Fairfield Ct. area wants to hear it drop me a email.<p>00 S4
