Bump! Anyone had luck passing with downpipes left in? If so what was the procedure...did you use a dp fix or what? Im too lazy to pull them out unless I REALLY have to...
Appreciate any help....Read through the thread but couldnt find the answer since the OP went back to stock in order to pass...Thanks in advance
