Exhaust Full Velocity / AC 6000 R XC (14'+) Category_Default Category/SLED/Ski-Doo/GEN5 850 E-Tec Turbo-summit Whether you want to maximizeThis is a great muffler for those looking to keep quiet down low but like a little bark once in a while! From idle to 1 3 throttle you can barely tell this is not a stock muffler. In the mid range you will notice a nice deep tone a little louder than stock. When you hit higher RPM this muffler has an exceptionally good tone without being obnoxious. This muffler has special thermal barrier and internal packing that keeps it very cool on the outside.
