FMF 020156 Gnarly Pipe Exhaust System for Yamaha - YZ250/WR250

The FMF Gnarly Pipe is a high-performance exhaust system engineered specifically to enhance low-end and midrange power delivery on two-stroke Yamaha YZ250 and WR250 motorcycles. This expansion chamber is designed for off-road riders who need maximum traction and torque in demanding terrain conditions.

Key Features:

• Optimized for tractor-like bottom-end pull with thicker, more usable midrange power
• Rugged 18-gauge steel construction built to withstand the rigors of off-road riding
• Nickel-plated finish provides excellent corrosion resistance and long-lasting durability
• Includes all necessary O-rings for proper installation and sealing
• Direct bolt-on replacement for stock exhaust system

The Gnarly Pipe's unique design shifts the powerband lower in the RPM range compared to FMF's racing-focused pipes, making it ideal for technical trails, woods riding, and situations where maximum traction and controllable power are critical. The durable nickel finish resists rust and maintains its appearance even in harsh conditions.
