Offroad Catalog

Features

• The most copied expansion chamber in the world
• All Gold Series pipes are computer designed and dyno tested to focus power gains where each machine needs it most
• Every pipe goes through the Tru-Flo stamping process to ensure quality performance and optimum fit
• Different pipes for selected models allow fine-tuning of a bike’s powerband – SST pipes are industry benchmark; Fatty pipes offer better bottom and top power; Gnarly improves low- to mid-power with a little less on top than stock
• The fastest pipe on the planet
• SST technology is dictated by the trademarked module on the back of the pipe that accelerates exhaust flow and substantially improves performance
• Using FMF Tru-Flo manufacturing technology, SST systems have computer-designed dimensions that mate to the SST module
• Constructed of strong 19-gauge steel with a chrome-plated finish
• Based on the successful exhaust pipe used by pro riders
• Cone section is shaped like the original Fatty but with new features
• Constructed with two thicknesses of steel
• 19-gauge steel used on the header portion for optimum strength and durability; 20-gauge steel on body and rear section for increased weight savings
• Seams are hand pounded after stamping process for that factory look
• Comes in a raw, unplated, oiled finish
• Computer designed and dyno tested to make power gains where each machine needs them the most
• Tru-Flo stamping process ensures a perfect fit and optimum performance
• Constructed of strong 19-gauge steel with a nickel-plated finish
• Power gains are focused toward bottom and mid, with a goal of increased tractability
• An excellent off-road pipe, and a winner for tighter tracks
• Built with tough 18-gauge steel
• The most popular 2-stroke silencers in FMF’s arsenal
• The elliptically shaped bodies with perforated core perform well in any condition
• Equipped with a Performance Flow end cap and nickel-plated front stinger
• The Shorty Silencer is the most desirable silencer for supercross performance
• Overall length of canister and core is shorter to improve the hit of your machine
• The SST Shorty Silencer is the heart and soul of the SST power package; required on some models when installing an FMF Gold Series SST pipe
• Tagged as the lightest silencer made, the Ti-2 is the direct result of FMF’s commitment to factory-level racing
• A full factory-level racing silencer provides stunning performance
• Spark legal muffler system meets the 93 dB sound level set by the U.S. Forest Service
• Long oval canister and internal technology provide optimum flow
• Straight-through design of the spark arrestor canister and the Performance Flow stainless steel end cap ensure strength, durability and unrestricted power
• Turbine Dampening System provides U.S.F.S. legal status
• Power Core silencers give your bike a deep works-like tone while providing optimum, dyno-tuned performance
• Silencer body is constructed of 6061 T6 grade aluminum with machined mounts and a clear anodized finish to bring out the shine
• FMF also offers the Turbine Core spark arrestor system which eliminates the exhaust restriction associated with conventional spark arrestors
