MINI 2" bore twin box Maniflow exhaust system. Rear side exit in the standard position for your Mini Cooper. If the 1.75" bore of the RC-40 isn't enough and you want to make it better, and louder, this 2" Maniflow system is for you. Very high quality, with skid plate on the bottom of the mufflers and gusseted pipes. Requires use of large bore LCB or 3-1 header. Recommended for Mini Cooper 1380s or screaming 1275s.
