Will a test pipe on a stock exhaust with a ractive muffler bring anything negative to the car?? don't want to put it on if its going to create more back pressure or anything of the sort..
So I'm putting everything back together and need a question answered before I can finish her up... when installing the manifold and turbo assembly, is the coolant line from the thermostat to the rear of the turbo supposed to be touching the water pipe??
