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 Warrior features proven four-stroke technology with a mighty 348cc single-cylinder engine. For even more optimal engine performance, the Warrior is equipped with a large 36mm Mikuni carburetor, which features both slide and butterfly valves to increase air flow and fuel delivery. We were able to take real advantage of this unique design by picking up 8% horsepower with our Sport Series Slip-On exhaust. The sound increased 4-6 dB, however, if you need to run quiet from time to time, install the HMF Quiet Core for a 2-4 dB cut.
