FMF Gold Series “Gnarly” Exhaust – Built for Torque. Ready for the Trail.

Designed specifically for off-road riders who demand maximum durability and low-end power, the FMF Gold Series “Gnarly” Pipe is the ultimate torque-focused expansion chamber for late-model 2-strokes. Built with heavy-duty 18-gauge steel and tuned for aggressive off-road terrain, the Gnarly pipe delivers increased bottom-end grunt while standing up to the punishment of extreme trail and enduro conditions.

Key Features:

  • Electro-Nickel Plated Finish
    Corrosion-resistant, non-chip coating maintains a clean look and prevents discoloration.
    (Note: Factory version features hand-pounded welds with no coating for a raw, works-style appearance.)

  • Heavy-Duty 18-Gauge Steel Construction
    Thicker material adds strength and impact resistance, ideal for harsh off-road environments and technical terrain.

  • Torque-Boosting Powerband
    Tuned specifically to deliver strong, controllable low-end and mid-range power, making it perfect for tight woods, hill climbs, and technical sections.

  • Built for 200cc and Up 2-Stroke Engines
    Optimized for larger displacement bikes that need more torque in slower-speed, high-load conditions.

  • Trail-Tested Durability
    The rugged construction and focused tuning make the Gnarly pipe a favorite among off-road racers, enduro riders, and hard enduro competitors.
