Ok guys first off, I DID SEARCH BEFORE I DECIDED TO POST A NEW THREAD. I just wasn't finding the answers I was looking for. Right now I have a mac prochamber and dynomax bullet race mufflers. I am getting MAC Long tubes very soon. I need a new mid-pipe and I just can't seem to find a used prochamber for long-tubes for cheap. Should I go with an offroad X pipe? I know straight through mufflers work good with x-pipes so it is either an x-pipe or another prochamber. I also want LOUDER, my setup is too quiet right now and I know LT's will help out WOT, but what about idle? If I go with an X, would the idle be a little louder? My main question is, switching from a prochamber to a mac offroad x pipe.. will I lose any power? Like a significant amount? Also.. will other brands of x-pipes for longtubes work with the MAC Longtubes? (i.e. Pypes)... Thanks to anyone who replies/helps.
