Product Details

The FMF Fatty Pipe is the most copied expansion chamber design in the motocross world, delivering proven performance gains for KTM 125SX, 144SX, and 150SX models.

Key Features:

  • Delivers a broader, smoother powerband for enhanced rideability
  • Durable nickel-plated finish resists corrosion and maintains appearance
  • Includes replacement O-rings for proper installation and sealing
  • Precision-crafted 100% in the USA to FMF Racing's exacting standards
  • Direct bolt-on replacement for stock exhaust pipe

The nickel-plated construction ensures long-lasting durability while providing excellent heat dissipation. This expansion chamber is designed to work with stock or aftermarket silencers for a complete exhaust system upgrade.
