4-1/2" MK45 Performance Mufflers - Chrome with Black Thruster
Upgrade your motorcycle’s exhaust presence and performance with S&S Cycle MK45 Performance Mufflers. Designed for riders who want a deeper exhaust note, responsive power delivery, and a distinctive custom appearance, these touring mufflers combine proven S&S Cycle performance technology with a premium chrome finish and contrasting black Thruster-style aluminum endcaps. Part number 550-0619 is engineered for compatible touring applications and delivers the fit, finish, and sound expected from a respected American performance brand.
The MK45 mufflers use a stainless steel baffle combined with RaceTEX cartridge packing to help produce a deep, controlled rumble without sacrificing performance. This internal construction is designed to support improved horsepower and torque while maintaining a refined exhaust character suitable for both everyday riding and long-distance touring. The result is an exhaust upgrade that adds stronger visual appeal and a more authoritative sound to your motorcycle without relying on excessive styling or unnecessary complexity.
A removable dB reducer is included, allowing riders to adjust the exhaust character according to their preferred sound level and riding environment. The chrome muffler bodies provide a bright, durable appearance, while the black Thruster endcaps add a sharp contrast that complements a wide range of motorcycle finishes. S&S Cycle manufactures these mufflers in the U.S.A., reflecting the brand’s long-standing focus on performance, craftsmanship, and practical rider-focused design. These mufflers are not intended for trike applications, so verify motorcycle compatibility before installation.
