2.5 vs 3.0 inch exhaust on turbo car??
how much of a hp gain you guys think I will get by upgrading to a 3in exhaust? is it worth the money or just keep what I got??? Its on a 01 prelude with a greddy turbo kit 8psi boost.

Don't upgrade unless you plan on upgrading your downpipe as well. I would save your money until you can replace the exhaust manifold, dp, and exhaust. Then have your car retuned and you will be very suprised with the HP gains you've made, each car is different, so it's hard to tell you exactly. But there are some people that have gained almost 20whp, so I would just wait.

Well if you have higher HP goals down the road, you are going to need a 3"+ exhaust anyways, so you might as well. But also look into upgrading to a ramhorn......
