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.

FMF Power bomb header 2009 KLR 650

I ordered this when I got my Leo Vince pipe. I bought it mostly because it just plain looks cool and I was told it fit with my pipe perfectly. Install took all of 30 minutes and was simple. Really happy with the way it looks, think I will look into the heat shield before too long.

Quiet Sparky Works Well

I mostly installed this to remove the edge of the PC4 sound and to have a spark arrestor. The sound is quieter but not by a large margin. The spark arrestor allows me to ride in places I would otherwise be unable.

100% worth the money

Definitively a great muffler. Bought it with the FMF power bomb and gained some mid range and some considerable high power and it just sounds great. Of course, the increase was not huge but it gave me that "extra push" I was searching. The fit on my Yamaha WR250f 2013 was PERFECT. I don't know anything about mechanics and was able to install it in about 30 minutes.

Great addition to PW80

i bought this bike for my son and the previous owner had torn off the exhaust stating it was restrictive. Probably true but this new pipe fit great and installed in minutes. Looks great and is quiet. I think it actually helped the bike thru the powerbands. Doesn't seem to bog and is quiet and sounds like a bike should. thanks. 80cc Dad

FMF gold series fatty

I put this on my CR 250R to replace my stock pipe, it fit fine and only took like 15 minutes to put it on along with the power core silencer 2. Overall I'm happy with the product and the price wasnt too bad.

I wike it a wot.

Good stuff! It did quiet my bike down though. I recommend it to you and all your family members. Even crazy Uncle John. Your old header can be used to make a piccolo. That's about it. Gotta go ride!
