In the early 1970s, California native Don Elmer was an expert wrench for local friends and racers, helping to make their bikes the fastest on the track. The secret was in the exhaust systems, and Elmer had the process and products perfected to make any bike fly. It didn’t take long for word to get out, and soon, “Uncle Donnie’s Flying Machine Factory,” or FMF, for short, was founded. Production started with handmade pipes and exhaust systems, all crafted with an intense attention to detail, incredible level of craftsmanship, and high standard of performance.
Now, with a streamlined production and several years of experience and innovation under their belt, FMF has become an industry leader in exhaust systems, pipes, and products. Their reputation for crafting durable and high-quality products from premium materials has certainly helped FMF land that standing, but it’s not the only thing.
Racer-borne and racer-run, FMF has never forgotten why they got into the business in the first place, and their brand is so much more than just exhaust products. As a huge supporter of professional motorcycling and the lifestyle that comes with, FMF sponsors several race series and manufacturers an impressive casual line to give back to the community that has given so much to them. This dedication to the sport, along with the fact that their exhaust systems and parts are made in the U.S.A., from start to finish, are just some of the unique qualities that set FMF apart from the competition.
With parts and accessories for machines of various makes, models, and years, we stock a wide selection of FMF products that is sure to fit your needs.

It was a good pipe a start but as soon as I went down into some dirt it completely flattened it at the neck I've had other fmf pipes that have been beating on way harder then this smashed on rocks rolled down hills.

Haven't ran the exhaust yet but it most definitely did not come with the spark arrestor installed and no instructions for how to do it. So be aware of this when you buy it

I am incredibly grateful that RMMC caries the FMF brand as an aftermarket exhaust option. I ended up buying (yet another system for another bike) this spark arrestor for a 202 Sherco 300 that I picked up - the fit was great, and the installation was very easy. Overall, the quality of FMF still sticks out as a favorite to me, and I'm completely happy with RMMC and FMF once again!

Purchased for my sons 2025 TTR50E. Sounds 100x better than stock exhaust that came on the bike. Also noticeable power increase at the top end of 2nd and 3rd gear.
