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.

Installed in my yz250x. I'd used just about every other pipe but lost the bikes stock feeling and would miss power here or there. This pipe made a noticeable difference in the higher rpms and also didn't take away any of the lugging power from the bottom end needed on some of these West Virginia goat paths. Spray it down with WD-40 after a wash and hammer downRead All Reviews

This pipe sounds awesome. I should have purchased it sooner. Easy to install yourself. However it was missing the little machined screw to keep the spark arrester in place. I had to call manufacturers to get the size. I contacted Rocky Mountain ATV warranty department about it and never heard back so I went to Lowe?s and picked one up.Read All Reviews
