FMF Racing

FMF Racing has been the most recognized name in off-road exhaust since 1973, when founder Don Emler began building pipes out of Southern California. Today FMF designs and manufactures performance exhaust systems, pipes, mufflers and spark arrestors for dirt bikes and ATVs, proudly made in the USA.

Every FMF system is built to add power, cut weight and deliver the brand's unmistakable sound, with options tuned for everything from tight off-road trails to motocross racing. Whether you ride two-stroke or four-stroke, there's an FMF pipe engineered to match your machine. Not sure which system fits your bike and your riding? Ask us, fitment help is what we do, and it ships from right here in Canada.
