757121 Fits All 2017 2020 Touring and U S Domestic 2021 to Present

Give your bagger a bold, strong power curve with these Kerker Stout 4-inch slip-on mufflers. Designed to slide right onto your stock head pipes, these mufflers use a traditional core to maximize mid-range performance. They are not just for show; testing on a 2010 FLH showed impressive gains of 9.6 horsepower and 9 ft-lb of torque over the stock setup. The mufflers feature hand-crafted billet aluminum end caps with internal tapering and recessed fasteners for a clean, streamlined look. Sold as a pair, they deliver a classic, deep Kerker rumble that sits at about 97dB, providing a much more authoritative sound than the factory pipes while maintaining excellent rideability.
