FMF Factory Fatty Exhaust Pipe - 025222 - 2021-2023 Gas Gas MC 85

The FMF Factory Fatty Exhaust Pipe is designed to mimic the "works" or cone pipes used by Factory Teams. Constructed with the finest materials and attention to detail, it extends the power curve for improved bottom-end, mid-range and over-rev performance. This exhaust system is ideal for all types of riding, delivering noticeable gains.


  • 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 in 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
  • Come in a raw, unplanted, oiled finish, must be oiled after washing - looks great in raw steel
