Well today Me and my friend who had a couple GTP's made a cai out of PCV. Used a 45', a 22.5' to angle it perfect and made the opening in the fender well slightly bigger so the most part of the cone filter sits inside the fender away from the heat of the engine bay. I must say I love the sound improvement snf it def seems to have helped the performance espically up top. I'll be painting it this week so it dont look quite as gay lol and then post up a pic, tell me if it looks like a decent setup.
