Aggressive track-designed exhaust system providing maximum flow and power. This system is substantially lighter than the factory system and flows much better. Recommended primarily for DE and track use. Includes Deluxe Bolt-On Dual Style Tips. Street legal emissions legal light weight track oriented DYNO developed system.
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
