I got a simmi on mine. They made it at 400mm length so is bs stamped. Very nice quality and sounds nice with baffle removed and not offensive to the ears. Only slight gripe is connecting pipe is an extremely tight fit on original downpipes. Don't know about the Delks but im sure they are good quality. But if you go for simmi you wont be disappointed.
