I have searched EVERYWHERE and I can't find what I'm looking for: I need to know the optimal exhaust pipe size for this application (3.0L Turbo). I'm leaning towards 2.25" for the up-pipe and 2.75 or 3" for the down-pipe. I want to keep it a little small on the hot side to keep the velocity up to keep the turbo spooled for quick response. I would greatly appreciate your advice/links to resources!
