I am not doing downpipes since I have been told not to bring the car in if they are on even if they are the catted ones. I would need to swap back and fourth for fuel pump bs and it's to much of a pain. Intake I can swap back and fourth no problem. It's going to be interesting what they say about my OCC. The dealers up here are all of sudden not mod friendly at all.
06Arctic, My sincere condolences .
