This Ultra-Lite™ silencer for the 600 G5 and 850 Summit and Freeride was designed with the competition racer in mind. It provides up to 7.1 pounds of weight savings. It passes the stationary sound test below 88 decibels but gives a more exciting sound at the higher RPM ranges (several decibels louder than our quiet version at wide open throttle). Throttle response is also improved slightly over our quiet silencer.
