Im looking into the ash spec intercooler piping but not sure if its going to help me? Off of what I have read its not a huge difference. I have sport 500 I belive (4 bolt) turbos with a 2.75 exhaust with im also debating when j change it if to go 2.5 or 3 inch exhaust. I have stillen intercoolers which I would have to upgrade to massives. And my throttle bodies are port matched to the plenum. What do you guys think is best decision?
