3" Pipe - pretty much unrestricted front to back. Not sure if ATEB bent the pipes or sends them out but man what an awesome exhaust
Pretty sure they just buy the mandrel-bent U-tubes and cut and weld as necessary. There aren't many people in the lower mainland that can mandrel-bend 3".
My truck showed up from Japan with 2.5" mandrel-bent stainless exhaust and a stupid cannon with a 6" tip on it. Of course there were also the pair of 2" crush bends right at the downpipe.
