FMF Factory Fatty Exhaust Pipe - 025101 - 2009-2023 KTM 50 SX

The Factory Fatty has been designed to echo the "works" or cone pipes utilized by Factory Teams, boasting superior quality and craftsmanship. The Fatty provides a broader and smoother power curve, increasing output in the low-end and mid-range, as well as providing a healthy over-rev. Regardless of your style of riding, the Factory Fatty has the enhanced performance benefits you need. If you need that performance edge look no further. 


  • The cone section has the same contours as that of the traditional Fatty exhaust pipe, however, it also has several advanced features.
  • Constructed with two steel thicknesses
  • 19 Gauge steel used for the header portion.
  • Lighter 20 gauge steel used for the body of the pipe.
  • Seams are hand pounded after the stamping process for that factory look
  • This Factory Fatty Exhaust Pipe is constructed from raw, unplanted steel and requires oiling after washing for a clean, trick look.
