This muffler looks the same as the 600 version, but they are NOT the same. Comes standard with our anti-bog deep snow technology, so when you are in deep snow and the exhaust caps off or plugs up there is an outlet or release point for the exhaust to exit so the sled does not bog or hesitate. This muffler uses all of the stock mounting points and hardware. It comes with the new Speedwerx performance guarantee to assure you it will not hurt the performance of your machine. Our extensive testing process and years of experience allow us to offer this performance guarantee. We started testing these mufflers in March of 2024 when the sleds were first released. We have tried and tested several different versions and variations to ensure we have the best muffler options on the market. L2 Competition Series Muffler is made out of titanium for the best appearance and longest lasting finish available. This is our light and loud version if you do not want a loud muffler do not get this version.
Updated pics coming soon, dB Info coming once production versions are on the snow.
This is the light and loud version. If you do not want a loud muffler, do not get this version. The Speedwerx lightweight Muffler is the one you want!
