Product Information

FMF Factory Fatty Pipe
  • Based on the successful exhaust pipe used by Team Yamaha's David Vuillemin, Yamaha of Troy and Team KTM
  • Cone section is shaped like the original Fatty but with new features
  • Constructed of two thicknesses of steel; 19-gauge used on the header portion for optimum strength and durability and 20-gauge steel body and rear section for increased weight savings
  • Seams are hard pounded after stamping for that factory look
  • Comes in a raw, unplated oiled finish
NOTE: Most Big Bore Exhaust pipes and silencer must be used with one another.
