Description

The HMF Performance Series slip-on exhaust system is designed for the Yamaha YFZ450R and YFZ450X. This system features a single 4-inch aluminum silencer that increases horsepower and torque while providing a better tone than the stock exhaust. It is significantly lighter than the stock silencer and includes the necessary hardware and mid-pipe to connect to the factory headpipe.
