Hey guys i am planning on getting a new midpipe soon, but i am indecisive as to what to get. I have the Magnapacks and I heard it with the x-pipe and the prochamber from Mac. I love the sound of the prochamber, but i wont be emissions legal. So i do not know what to do. A lot of people tell me to get o/r H pipes but is there that big of a difference between catted and o/r?? Would i feel a difference if I got the catted version of the h-pipe??
