New for 2019- Stainless Steel muffler that's even lighter than the previous steel version at the same price! Our new adjustable muffler allows the back pressure to be adjusted for better acceleration and throttle response to put you out in front of the competition, and it saves nearly 9 lbs. too!

New ISR Snocross rule for 2017-2018 and beyond-  All Pro & Pro Lite sleds may use a commercially available aftermarket can/silencer!

Disclaimer: designed for competition use only! Speedwerx, Inc. is not responsible for the performance or noise of these exhaust systems. These exhaust systems are designed to be lighter and louder than our original lightweight muffler systems. The mufflers are suggested to be used for closed course racing only.
