Holy Crap, I took out my cat and never would of thought how restrictive it was, I put in a 2.5 in test pipe. It kinda smells like *** when idling but it was worth it. The throttle response is 10 times better, I would stongly recommend it !!

Not with a turbo it doesnt really change the sound, in fact in should sound better.. Whats really cool is running straight pipe with a turbo, you can hear the turbo spooling down after you drive it... very sexy..

I have a resonator pipe instead of my cat and it sounds great. The turbo spools up REALLY fast with a straight exhaust. It starts spooling a 2000rpms and gets full boost (8psi) around 3000rpms pull hard as hell!

Yes it is actually a little louder while not boosting, but when boosting its is ok.
