The MK45 4-1/2" Touring Mufflers are the result of decades of riding, racing, and tuning. They combine both a stainless steel baffle and RaceTEX cartridge packing to create a deep rumble while improving horsepower and torque. The unique look is enhanced with styled aluminum endcaps. Additionally, they feature a removable dB reducer and are made in the U.S.A. Please note that these mufflers are not for Trike applications.
