Right now I am preparing for a turbo setup. I had my eyes on the RSR-Ex Mag exhaust. But i'm guessing that this would be a bad exhaust with a turbo setup due to the restriction. So, i didn't want to have a really loud exhaust but it doesn't look like i have much a choice. What would be a good exhaust to get with a greddy turbo setup. Greddy EVO? APEX N1? i'm trying to have a quiet exhaust too by the way
