I have a pacesetter cat back and was wondering when I went turbo if I would need to get a 3in exhuast? Thanks

2.5" is enough.

just curiuos, an exhaust system for a na gs/rs should bolt right on to a gst, right? gsx might be a little different?

Correct, but the stock muffler would choke it pretty good. You probably couldn't get more than a few psi of boost.
An aftermarket 2.5" catback designed for an RS/GS would bolt right up to a GS-T with no problems.

well i just recently installed a custom 3" exhaust w/ no cat, and the same revolution muffler and i love it! i have way better power gains especially at the top end. it's not raspy and sounds a lot better than when it was stock piping. i told the shop to add a resonator so it could quite it down a bit. the whole job was awesome and it was done for $165. sweet deal.
