FMF Factory Fatty Pipe Yamaha YZ85

The FMF Factory Fatty Exhaust is reminiscent of the “works” or custom cone pipes once used by Factory Teams when two strokes ruled the dirt. It shares many of the same characteristics with its factory works predecessors including the craftsmanship and material quality. Constructed with two thicknesses of high quality carbon steel, the lower portion is comprised of 19 gauge steel for optimum strength and durability, while the upper section is made of lightweight 20 gauge for improved weight savings. Much like the Gold Series Pipe, the Factory Fatty was designed to broaden and smooth out the power curve, while boosting gains throughout the entire power band, offering more low-end, more mid, and increased over-rev. If you are looking for a lightweight, all around power enhancing pipe, the Factory Fatty fits the bill.


  • Lighter 20 gauge steel used for the body of the pipe
  • 19 Gauge steel used for the header portion
  • Hand pounded seams for smooth flowing transitions
  • Weight: 3.0 lbs
  • 100% Made in the USA
