ok so this has been in another one of past posts, but the guy who tuned my mustang told me that the prochamber is crap and is raping me of a good at least 10 horse, so i ordered an xpipe and im gonna get my mac mufflers and pipes for the time being, now, what are some of your guys opinions on this ive been told that in the upper rmps is where the xpipe really shines, but i dont know i would just assume its all the same crap its just routed a little different, my mods are full bolt ons + gears andvt stageone cams, soo dump the prochamber and get an x? or the other way around?

I'd go with the X, but thats just personal preference, that has nothing to do with performance.

The X will give better performance but its more like maybe MAYBE 2-3 horses.... Prochamber is soooo quiet compared to the X .
