Just a review of the new cat-back system I got install this past Friday.

It's freaking awesome! I brought my car in to get checked a couple of weeks ago because I had a leak in my flex pipe. It turned out to be my downpipe/flex pipe joint was hanging together by 1 and a 1/2 bolts and my rear muffler was also just hanging on by a thread as well. My whole system had to be changed, so instead of going OEM, I decided to go with a full system.

The guys at RPI talked me into getting the Neuspeed system with a Techtonics cat (because it was about that time to get the cat changed too, although there was nothing wrong with it).

I was kind of second guessing getting an aftermarket because I didn't want it too loud or droning, but after getting the Neuspeed, I'm glad I did it.

It's got a really subtle low rumbling sound upon ignition. On acceleration, the loudest it gets is at 2500-3000 rpm, then it trails off to being not much louder than stock. On highway speeds, you can hear it being a bit louder than stock only. All in all throughout, the loudest parts are at ignition and hard acceleration. All other times, it's just got a nice deeper grumbling.

Labour at 4-5 hours, but for rates, should call RPI... they did something special for me, so I don't know what the regular rates are.

do you guys know how the neuspeed system sounds on a B6 S4? I am getting one, but can't decide on resonated v. non-resonated.
