The new DG RST (Reduced Sound Technology) muffler is the quietest DG muffler and is designed especially for dual-sport machines (Just 84db @ 3200 RPM). A new baffle design dissipates sound waves reducing noise output in a very efficient manner. This new design also stretches out the time between muffler repacks. Included is a Stainless Steel mid-pipe, USFS Approved Spark Arrestor and a new Aluminum end cap.
