Maybe I'm crazy but most likely stupid, but are intakes more than just mandrel bent 3" pipes with a port off to the side for vacuum hoses? I mean, maybe I'm just a cynic, but it seems to me these companies are charging an arm and a leg for these things. Is there something on the inside of these pipes that make them special?...PLEASE tell me so. DO NOT POINT ME TO PAST POST because I have spent a couple of hours reading through them. I'm just curious. HOLLA!
