FMF has produced innovative exhaust systems since 1973. Flying Machine Factory(FMF) has its roots primarily in the Dirt Bike exhaust market, but today also produces FMF exhaust for the Sport Bike and ATV markets as well. Whether you are looking for FMF head pipes to fit your 2-stroke or a complete FMF exhaust system for your 4-stroke Dirt Bike, you've come to the right place. Here at Dennis Kirk, we carry a huge selection of FMF exhaust as well as FMF clothing and accessories. From FMF exhaust and handlebars to hoodies and hats, we carry everything you might need from FMF Racing.
FMF exhaust was first created in the garage of Don Emler and was one of the first aftermarket motorcycle exhaust manufacturers. Emler was known as a mechanical prodigy after he began competing as a professional motocross racer. With racing experience, Emler knows what is needed to create a high performing dirt bike exhaust. FMF ATV and dirt bike silencers are some of the favorite among riders. PowerCore Slip-On silencers will keep your sound levels where you need them without sacrificing power. When you want power, FMF PowerBomb headers are what you need.
Once you have the FMF exhaust that you need, make sure that you are getting the right fuel mixture to take advantage of the exhaust. When you put a performance exhaust on your dirt bike, you most likely will need to change your fuel mixture. The FMF Power Programmer will automatically tune your bike's EFI to match your riding style. If you have carbs, an FMF Power Up jet kit will allow you to extract maximum horsepower and torque from your dirt bike or ATV.
