RE: turbo exhaust

2.5 is prolly th biggest you want, 3 inch for pretty much bt only, small turbo with a 3inch will hinder performance (little to no back pressure), small exhaust with a large turbo too much backpressure, not good.

RE: turbo exhaust

Downpipes will make the biggest difference, so make sure you get a new one. 2.5" TB is good.
