First of your an Idiot for racing in your Xterra and I am suprised no one told you that. Second off if you would have searched I have posted in numerous threads about the gibsonm exhuast and the fact that it dose not exit out the side. You cant run an exit out the side of the new x's because of how the leaf springs are mounted. And if you want loud go buy a honda and put a fart can on it.
