I been searcin for an exhaust, and i had my eye on the Apexi N1, but the question is should i buy the whole cat bac w/ the pipin or just buy the muffler and get the pipin at the shop?? Does anybody has the N1? WHat did you do?? Thanx

I've got the cat back N1 and it sounds awesome. I've also got a test pipe and 3 inch downpipe so that could have something to do with it.

I had a catback, I wouldnt just put a muffler on. I thought it was a bit too noisy, but increased high end power with the turbo. Putting the baffler on, killed most if not all the gains
