S&S Cycle 4-1/2 Inch MK45 Performance Slip-On Mufflers for 2017-2024 Harley-Davidson Touring

Touring riders who want a deeper, more authoritative exhaust note without surrendering street legality need a muffler that meets both demands without compromise. The S&S MK45 slip-ons deliver a deep throaty tone from a multi-layered acoustic packing system that stays consistent for the life of the muffler, and the lava chrome finish brings a distinctive look that stands apart from the standard chrome or blacked-out options on the market.
