Call attention to your ride without calling attention to your ride. Tuned to provide a deep base exhaust note and great rumble throughout the RPM range, these 3.5" Street Cannon mufflers deliver the famous Harley? sound while preserving the peace with your neighbors. You get a nice bark when you get on the throttle, and a deep mellow tone when cruising at constant speed. The tuned baffles work with the internal high-flow catalyst to strike the perfect balance required to deliver performance that you can feel in your gut. The large 3.5" diameter Street Cannons provide free flow of exhaust gases with just the right amount of back pressure for a smooth-running ride. Mufflers include matching chrome end caps with subtle engraved Screamin' Eagle? logo. Looking to black out your ride? Optional satin black wrap-around muffler shields and end caps are available to complete the look.
