About FMF
Over the decades, FMF seen an amazing transformation in the world of motorcycles and ATVs. The progression of the technology is one of the challenges that keeps FMF going.

Their goal will never change - take the most advanced machinery to its limit by building the world's best performing exhausts. And its a fact, they build every exhaust by hand from start to finish right here in the U.S.

At the end of the day, there is always one major force keeping them motivated—throwing a leg over the bike and heading for the trails or the track. Their biggest reward for is knowing they're helping customers get the most out of their riding experience. They still ride every chance they get so they never forget why they got into this business in the first place.
