TurfBurn said:You are concerned that 3" won't be enough??? I guess my additional surprise from that standpoint is Terry got over 250 with my car and it has a tiny 2.25" downpipe, and the flange was welded poorly and the exhaust outlet of the turbo had a 20% restriction.
It is not a 3'' DP. It is a dual setup. 2.5'' and 1'' into a 3''. My gut tells me the one 3'' would have worked better.
