Have you seen the new Factory Fatty pipes? They're rough, and hand-welded and look like you just stole it off of David Vuillemin's bike. FMF pipes have the most copied expansion chamber in the world. Their pipes are computer designed and dyno tested to focus power gains where each bike needs it most.

Fatty pipes are designed to give the engine an all around power increase. They do not drastically altering the power band of the bike. This pipe will appeal to most people that are happy with the stock power band and just looking for more useable power everywhere.

If you're really looking for that factory silencer, new for this year is the Titanium 2 FMF exhaust silencer. With the titanium stinger, front cap and cone end cap, you'll shave off tons of weight. Gains will be similar to the Powercore 2 Shorty.

The Turbinecore and Turbinecore 2 are theForestry Approved spark arrested silencers. This FMF motorcycle exhaust gives you that factory look and power yet still being Forestry legal. This isn't something you'll have to take on and off, like what has been offered in the past.

Also new for this year is the "Q" silencer which takes our Turbinecore 2 to the next level of being sound friendly. This FMFexhaust system is the quietest silencer FMF has ever offered. This also has a Forestry Approved spark arrestor.

The Motocross Action Magazine crew got their paws on the KTM520X Titanium Exhuast system. They loved it. Their bottom line: "This is a no brainer. The FMF Titanium exhaust system produces more power, better power and a broader power band, while knocking almost five pounds off of the bike." FMF is not only the world largest off-road exhaust manufacturer, but their new PowerCore-S street exhaust brings some unique features into the sport bike world as well.
