4-1/2" MK45 Performance Mufflers - Black Thruster
Upgrade your motorcycle’s exhaust system with S&S Cycle Mk45 Touring Performance Mufflers in the Black Thruster finish. Designed for riders who want a deeper exhaust note, improved performance, and distinctive styling, these mufflers combine decades of S&S Cycle riding, racing, and tuning experience into a durable bolt-on performance solution. The Black Thruster finish and styled aluminum endcaps provide a clean, aggressive appearance that complements a wide range of custom and touring motorcycle builds.
The Mk45 mufflers use a stainless steel baffle and RaceTEX cartridge packing to help produce a deep, controlled rumble while supporting improved horsepower and torque. This combination is engineered for riders who want enhanced exhaust character without sacrificing the fit, finish, and long-term durability expected from S&S Cycle components.

Their touring-focused design makes them well suited to street and long-distance applications where sound, appearance, and responsive performance are important. Before installation, confirm compatibility with your motorcycle and exhaust configuration. These mufflers are not intended for trike applications.
