wassup guys, i got a stillen exhaust and i'm looking to get a cattman y-pipe. i plan to call custommaxima real soon to place an order. any suggestions on which y-pipe to get? i remember a post a looooong time ago saying that there was a rumbling sound from his y-pipe.. has that been fixed? will there be any problems that i will have to deal with from installing the y-pipe? sorry guys i would have used the search but its not workin. thanks in advance!
