I`ve been reading up on this inlet pipe and ran across two.... The ATP 3 turbo inlet kit and the RPMC kit. I read a review on the RPMC one and it sounds like a great upgrade. I have not found a review on the ATP one though and would really like to compare the two. I was wondering if anyone has used the ATP kit and what they thought about it.... Any help would be greatly appriciated. Thanks everyone! By the way this site is the shisnit!!!
