FMF Fatty expansion chamber
35 years of racing experience: The FMF factory pipes have been specially developed for the hardships of offroad life. That's why they're made from high quality, extra thick, hardwearing sheet steel. An elegant appearance is ensured by the nickel-plated surface. For years and years.
Additional features:
- Broader and more usable rev range
- Higher top speed
- More traction, better control when accelerating
- Nickel-plated surface
- Including O-rings
For a perfectly tuned and performance-optimized overall system, we recommend combination with an FMF factory or Six Days silencer.
