Today, HMF is a leading worldwide supplier of performance exhausts for the Powersports Industry. Pushing the limits in our research and development is how we come up with new ways to solve the needs of off-road riders. HMF is on the front line of Powersports engineering to keep riders, like you, moving ahead towards the next adventure.

The Performance Series exhaust has been the staple of the brand since the origin. Whether on dirt or pavement, this exhaust system has the capability of generating an even increase in horsepower and torque while distributing that signature HMF tone.

The Yamaha Raptor 90 is available as a Full System in the Performance Series exhaust. The shell is a miniature version of the standard Performance, and features an internal core that is sure to make the most of these smaller engines. There is typically a 10-15% horsepower and torque increase on the Yamaha Raptor 90, and the sound level should be roughly 2-3dB louder than the stock muffler.
