Yea its the valve I was talking about, its just so freaking loud, guess I shouldnt of straight piped it and had it exit b4 the wheel,lol.

Just wanted to say it is the cold weather. You think it is loud in the X. You should try 6" stacks behind the cab and it making that noice driving down the street. O'well at least it will be ok.
