Description

Constructed from durable 304 stainless steel and finished with a mirror polish, this dual muffler offers both performance enhancements and a refined aesthetic. Designed for optimal performance, the system features 2-inch tubing from the muffler to the tip, which helps maintain exhaust gas velocity and maximize horsepower gains. The connection into the muffler remains at 2.5 inches to ensure maximum flow. Version II improvements include reinforced hangers and enhanced insulation for a mild sound profile. This exhaust system comes equipped with removable baffle inserts in the 3-inch tips, allowing you to control the final sound level. You can choose a sporty sound with the baffles in, a louder tone with them removed, or opt for additional baffles for the mildest sound. The RoadsterSport II Dual Muffler is a straightforward bolt-on installation and includes all necessary hardware, including a gasket. It is backed by a lifetime warranty.
