Actually, not many do at all... Don't go porting anything yet. You're still on the stock turbo. It'll be awhile before you NEED porting.
Tony if that statement was true then he certainly doesnt need a 3" exhaust or a downpipe for a t25. But since he wants to get maximum exhaust flow he should port the o2 housing and stock manifold.
I agree. Free'er flowin exhaust certainly won't hurt you, he just probably won't see big gains, if any. Also check out Megan Racing. They seem to make very good products for cheap money. I myself have a Road Race Engineering stainless steel down pipe that has worked out very well for me. It is also 2.5" up to the just after the flex, where it grows to 3".
