FMF

The Flying Machine Factory. It all began in 1973 in a tiny garage in California, Donny Emler (founder) had a passion for dirt bikes and began building 2 stroke pipes. Donny captured the public’s eye for how fast his bikes would ‘fly’ and they wanted in on the exhaust power!

Today, FMF exhausts are still based in Southern California but that tiny garage is now a 100,000 + square foot state of the art manufacturing facility! FMF Exhausts are the only Southern Californian company that produce everything under one roof! From start to finish FMF Exhausts are 100% American made – what company can claim that?!

Founded on 2 stroke technology, FMF manufacture both 2 & 4 stroke mufflers and supply exhausts pipes from as far back as 1986 with dirt machines ranging from 50cc to 500cc. Derived from the race track, FMF provide economical exhausts such as the Powercore 4 right through to the ‘race ready’ Factory 4.1. Exhausts are available in stainless and titanium and all designed to improve the torque and increase the horsepower.

The progression of the technology is one of the challenges that keeps FMF going. FMF was there in the days when the singleshock and watercooled engines were huge innovations and now for the aluminium chassis and electronic fuel injection. FMF’s goal will never change - take the most advanced machinery to its limit by building the world's best performing exhausts.

FMF are involved in all levels of racing, from amateur grassroots SX & MX racing right through to AMA and MXGP. FMF work closely with the Athletes and Factory teams such as KTM Factory off-road, Rockstar Energy Husqvarna & Star Yamaha to develop and produce the worlds best offroad exhausts.

At the end of the day, FMF are more than an exhaust brand – they love riding and it’s what they do. The major force keeping FMF motivated is throwing a leg over the bike and heading for the trails or the track. To this day, if Donny isn’t in his dyno room he can still be found out shredding the trails – now that’s passion!

Founded by the love of riding and driven by providing cutting edge performance - FMF live to bring you power!
