i was with you till you said cat. wtf you thinkin, that will kill your turbo spoolup time. turbos hate backpressure.
Right, but i still have to pass emissions...
cut out?
Besides, i really don't think it'll have much back pressure, most cat's on newer vehicles have zero back pressure from cats anyways, so i'm pretty sure this one won't have any, but cut out anyways.
