FMF Pipes

Since 1973, FMF Racing has been improving performance in the world of motocross, motorcycles, and ATVs. Founder and owner Don Emler started FMF in a garage in Hawthorne, California, not knowing the industry force the FMF name would quickly become. And although the company is clearly bigger now and many things have changed, the facts that matter stay the same: FMF still stands for serious high performance exhaust systems and Don Emler, also called “Uncle Donnie,” is still building and innovating FMF exhausts and accessories hands-on at their facility.

When you buy a brand like FMF, you're getting decades of experience within an industry where change is a constant. In the worlds of ATVs, motorcycles, and motocross racing, the technology is always changing. Thanks to owner Don Emler and the cohesive FMF team, there is a real institutional memory at FMF, and their designers remember each technological change that has come down the pike, from water-cooled engines to single shock motorbikes, and from electronic fuel injection to the use of aluminum to build the ultra lightweight, modern chassis.

FMF has a singular focus: to design and build the exhausts that perform the best, no matter what else changes. They take that focus seriously, and they make it their business to construct each and every exhaust in house here in America. Like you, and like us here at BTO Sports, the team at FMF is ultimately motivated by their own love for the sport and passion for riding. They want more out of their riding experience and they know you do too.

FMF Exhaust

Even those that are fairly new to the sport of motocross probably know that replacing your factory exhaust system with an exhaust system specifically designed for racing and high performance is one of the best ways to get more from your bike. An FMF exhaust system works by emitting exhaust gasses from your engine more quickly than your factory system can, making room for more oxygen and fuel in the combustion chamber of your engine. This means more traction and better power—in other words, more speed—from the same engine.

FMF exhaust systems deliver more speed and power without more noise, and they weigh less than your factory system so they reduce your weight. That's because of the highly efficient design of the systems and the superior materials they are crafted from—typically titanium. Each FMF muffler and header combo is designed to provide you with more power and performance.
