The geometry & design of the system produces a power curve that is suitable for flat-track racing. Linear, predictable, with good peak and over-rev horsepower. It parallels the OEM exhaust routing around the engine and exiting under the rear fender. The product is rubber mounted to reduce vibration. It is available with two different muffler options: 8" and 12". The 8" muffler has a marginally higher sound decibel and is used for non-pro racing. The 12" muffler is AFT-Pro racing compatible at 105 DB.
