Zippers Premium 4" SuperZip Mufflers for Scouts - 242-150
These mufflers feature a louvered baffle design that promotes early and mid-range torque, while allowing maximum HP at the top end. The result is an extremely flat torque curve, with an upwards kick right where you ride for instant acceleration while cruising. These mufflers have a deeper tone with a much more aggressive sound. An extra coat of nickel is applied before chrome plating for a deep shine and the 4” black tips add to the overall robust look of the SuperZip mufflers. Installation is very simple as no extra hardware or brackets are needed. Made in USA!
