Lighten up your snowmobile by replacing the stock silencer with SLP’s lightweight version. Each SLP silencer has been dyno tested and field verified to ensure maximum reliable horsepower while shedding the desired weight. Sound level emissions are a focus at SLP. We strive for a quality, robust sound and using the SAE J-2567 stationary sound test to ensure they meet the state adopted 88 decibel limit (refer to the chart below). All silencers are finished with ceramic coating which looks great and reduces radiant heat by as much as 40%, resulting in cooler underhood temperatures.
