PVC haha I dont use that crap....I didnt want my opinion to get all rowdy, no I do appreciate the fact that you care enuf to let k&n know we are interested, I myself have a weapon r setup, two seperate chrome pipes down in the wheelwell with a 60 dollar weapon r filter, I didnt use ducttape by any means, as a matter of fact I bought a maf adapter from u! I love my intake, everyone has their own way of doing it, some just want performance aka duct tape, pvc whatever, and some will spend 200 to get a nice one, I would, but I got mine done, no more arguments, REMEMBER I DO APPRECIATE EVERYONE here for making this club what it is today, thanks Mike, and everyone, thats all...
