HMF Racing Yamaha Warrior- Competition-Series Slip On 87-04

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% horse power 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.
