FMF Exhaust

FMF was in the exhaust business when single-shock and water-cooled engines were huge innovations. Over 35 years later, FMF is still innovating in the era of the aluminum chassis and electronic fuel injection. Over the decades, FMF exhaust pipes have earned the trust and respect of dirt bike riders and motocross racers around the world. FMF also makes exhaust systems for ATVs and street bikes, in addition to replacement exhaust parts and fashionable moto apparel.

Started in 1973 by owner and founder Don Emler in a garage in Hawthorne, California, FMF (Flying Machine Factory) was one of the first aftermarket manufacturers of motorcycle exhausts. Emler was a professional motocross racer who gained a reputation for being a motorcycle mechanical prodigy. FMF exhausts achieved national notoriety in 1974 when they powered Marty Smith to the AMA National 125 Championship. In 1988, the release of chrome-plated FMF exhaust pipes was a breakthrough hit. Then in the ‘90s when noise pollution became a hot issue, FMF exhaust products expanded to include silencers. Now, FMF exhausts and silencers are among the most popular for dirt bikes and ATVs, including PowerBomb headers and PowerCore Slip-On Silencers. Every FMF exhaust is built by hand from start to finish in the USA.

FMF travels to over 100 events a year and sponsors dozens of amateur and professional racers. As title sponsor of the KTM off-road factory team, FMF exhausts have powered WORCS champions Kurt Caselli and Mike Brown, GNCC XC2 champion Kailub Russell and National Enduro champions Charlie Mullins and Russell Bobbitt. Keeping you stocked with the gear of champions, Motorcycle Superstore offers a complete selection of FMF exhaust pipes, silencers and full FMF exhaust systems for your bike. Modify your ride with an FMF exhaust or silencer and aim your flying machine for new heights.

Excellent addition to bike. Sounds great, works great. Turns the bike into a proper moto. A little issue with fit due to some bent frame tabs. Didn't notice when installed originally, but once addressed all was good.

Pricey but Complies

Fifty bucks for this simple end cap/arrestor is a lot of money. That said, it puts your bike in compliance with Forest Service and BLM spark arrestor requirements. It does not reduce the noise level apprecialbly.
