{"title":"FMF RACING","description":"\u003ch2\u003eThe Flying Machine Factory - Performance Exhaust Since 1973\u003c\/h2\u003e\n\n\u003cp\u003eFMF Racing—the Flying Machine Factory—has been the gold standard in motocross exhaust for over 50 years. Founded by Don Emler in his Hawthorne, California garage in 1973, FMF started with one goal: go faster and have more fun. That obsession with performance turned into the most iconic exhaust brand in motocross history.\u003c\/p\u003e\n\n\u003ch3\u003e100% Made in the USA\u003c\/h3\u003e\n\n\u003cp\u003eEvery FMF pipe and silencer is handcrafted at their Southern California facility. In an era of overseas manufacturing, FMF remains committed to American craftsmanship. From raw materials to finished product, everything is built in-house to exacting specifications.\u003c\/p\u003e\n\n\u003ch3\u003e2-Stroke Exhaust Systems\u003c\/h3\u003e\n\n\u003cp\u003eFMF built its reputation on 2-stroke performance. The legendary Fatty pipe delivers all-around power gains throughout the entire RPM range. The Gnarly pipe maximizes low-end torque for off-road riding with heavy-duty 18-gauge steel construction. The Factory Fatty features hand-pounded welds just like the factory works bikes. Pair any pipe with a Powercore 2, Powercore 2.1, Turbinecore 2.1, or Shorty silencer for the complete system.\u003c\/p\u003e\n\n\u003ch3\u003e4-Stroke Exhaust Systems\u003c\/h3\u003e\n\n\u003cp\u003eFMF's 4-stroke lineup delivers serious performance. The Factory 4.1 RCT features Resonance Chamber Technology with aerospace-grade titanium construction. The Powercore 4 and Powercore 4 Hex deliver race-inspired performance at accessible prices. MegaBomb headers maximize exhaust flow for increased horsepower and torque. Available in stainless steel, titanium, and carbon fiber options.\u003c\/p\u003e\n\n\u003ch3\u003eTechnology \u0026amp; Innovation\u003c\/h3\u003e\n\n\u003cp\u003eFMF's proprietary technologies set them apart. Resonance Chamber Technology (RCT) optimizes exhaust gas flow for maximum power. Electro-nickel plating provides a durable, non-chip finish that won't discolor. The Turbine Dampening System in the Turbinecore 2.1 makes it the world's best-selling spark arrestor—U.S. Forest Service approved with unrestricted performance.\u003c\/p\u003e\n\n\u003ch3\u003eRace-Proven Performance\u003c\/h3\u003e\n\n\u003cp\u003eFMF exhaust systems have won more motocross and supercross championships than any other brand. As the Official Exhaust of American Motocross for over 30 years, FMF powers the fastest riders in the world. From Marty Smith in the 1970s to today's factory teams, champions choose FMF.\u003c\/p\u003e\n\n\u003ch3\u003eBike Coverage\u003c\/h3\u003e\n\n\u003cp\u003eWe stock FMF exhaust for Honda CRF, CR, XR, and TRX models.
