I just upgraded from a 99' to a 2002 w/6speed and was wondering how loud would a straight through muffler be with all the factory exhaust? I know that the 4th gen. were pretty mellow with the stock y-pipe. And what about the sound with just the aftermarket y-pipe not with headers (warpseed)?

Cattmans muffler is straight through and they sound really nice. It gets loud when you add headers, Highflow cat, and the b-pipe...
You cannot beat the cattman cat-back, great sound, SS and it looks great.
