There are people her making 500rwhp with 3 inch pipes (DonE).

I think you are fine with 3 inch and a cat/premuffler bypass into a factory C2 turbo second muffler is a hard combination to beat from what I have heard.

I have seen some writings that may indicate that 3.5 inch might be getting on the edge close to that but I think that is for longer run pipes.
