Mk45 4-1/2" Touring mufflers are the result of decades of riding, racing and tuning, engineered to deliver real-world performance.

They combine a stainless steel baffle with RaceTEX cartridge packing to produce a controlled, muscular sound and improved horsepower and torque.

Styled aluminum endcaps give a distinctive look while the removable dB reducer lets you tailor the exhaust note to your preference.

Made in U.S.A. and designed for touring applications; not for Trike applications.

Choose MK45 mufflers for a deep rumble, refined throttle response, and a custom appearance on the road. 🔧
