Mac pro-chamber and mac 2.5???
what is the difference in the pro-ch, and the regular 2.5 offroad, it sounds better? if so, why? isnt it just a 2.5 system too?
I want better sound, plus my current h-pipe is vibrating on my crossmemeber and driving me nuts, so i will sell mine and get another, perhaps an x-pipe. thnx....
