FATTY PIPE:
With well over 35 years of racing experience behind it, the Fatty Series pipe delivers race proven performance. The Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you’re looking for.

  • More tractable power, improved throttle control
  • Provides power gains throughout entire power band
  • Carbon steel with a nickel plated finish for maximum durability
  • FMF Racing’s Tru-Flo stamping process ensures a perfect fit and optimum performance
  • Can be used with FMF or stock silencer (unless noted)
  • FMF'S most popular 2-stroke pipe 
  • O-Rings included

FACTORY FATTY:
Reminiscent of the “works” or cone pipe once used by Factory Teams. It shares many of the same characteristics with its craftsmanship and material quality. The Factory Fatty broadens and smoothes out the power curve while boosting gains throughout the entire power band, more low-end, more mid, and increased over-rev. No matter what type of riding you do, the Factory Fatty has the benefits you’re looking for.

  • Lighter 20 gauge steel used for the body of the pipe
  • 19 Gauge steel used for the header portion
  • Includes O-rings on most models
  • Hand pounded seams for smooth flow transitions
  • O-Rings included

GNARLY PIPE:
Focuses on increasing the lower RPM horsepower and torque to get you out of the toughest terrain. When looking to add 4-stroke tractor-like torque to your 2-stroke, and you need a pipe to withstand the harsh elements, this is the pipe for you. Strong and rugged, this aggressive pipe dishes out handfuls of torque and bottom to mid range pull needed for late model 200cc - 500cc machines and the rigors of the offroad domain.

  • Nickel plating is an FMF trademark and has been ‘copied’ by everyone making it the most imitated expansion chamber in the world
  • Super strong 18 gauge steel construction makes it GNARLY!
  • O-Rings included
