The Supercup is significantly louder than our Maxflo Exhaust option, but if you're looking for a very aggressive exhaust note and you prefer Flat 6 symphony in maximum BD -  this is the system for you! If you want the best of both worlds, check out our TrackTec Valved Exhaust or our Valvetronic Exhaust, which will be slightly louder than the Supercup with the valves open and just as civilized as our Maxflo system with the valves closed
