Rocket Exhaust produces the only “octagonal” shaped exhaust systems. The unique shape of the muffler has superior noise canceling features, larger packing volume, is stronger, lighter and has better tire clearance than conventional designs. The muffler is available in aluminum and carbon fiber. The unique muffler mounting system insures a “happy” fit utilizing our moveable hanger bracket and precision mid-pipe to muffler slip-fit. Head and mid pipes are constructed from an air-craft quality stainless steel and each model is dyno tuned and track tested to optimize performance and power gains using Rocket “stepped” and or Rocket “tapered” tube designs. If you need to reduce the dB level Rocket offers optional Stealth Core inserts. Never before available to the consumer Rocket is introducing the ability to customize the length and internal core configuration of the muffler. Engine tuners rejoice!
