Kanga, this is making me think, so you are saying that by instaling only the 2 supersprint exhaust I will loss performance?
on the
SUPERSPRINT WEB SITE: WELCOME! page, they are refering to the "Front exhaust with metal Kat." part no 755032. Is this what you saying I should change as well?
I think it will take to long to get the cats over from Australia, not in time get it here by next friday 14th. (not sure if I get the car back from the garage before that anyway)
