    Yes - it bolts in after the cats, and extends to, just before, the OEM mufflers. W4M down-sized the ends of the 3" pipes leading to the mufflers, I think, so that they will slip over the 2 1/2" OEM pipes leading into the mufflers. Still a bit of back-pressure but a lot less than with the pinched OEM pipes.
