FMF 024054 Gnarly Pipe Exhaust System for Yamaha - YZ250

The FMF Gnarly Pipe is an off-road focused expansion chamber exhaust designed to deliver exceptional low-end and midrange power for demanding trail and enduro riding conditions. Engineered specifically for the Yamaha YZ250 two-stroke (1999-2012), this pipe transforms the engine's power characteristics to provide enhanced traction and control in technical terrain.

Key Features:

• Optimized for tractor-like bottom end pull with thicker, more usable midrange power
• Rugged 18-gauge steel construction for maximum durability in harsh off-road conditions
• Nickel-plated finish resists corrosion and maintains appearance over time
• Includes all necessary O-rings for proper installation and sealing
• Direct bolt-on replacement for stock exhaust system

The Gnarly Pipe's unique chamber design focuses on building power where off-road riders need it most—in the low to mid RPM range where technical riding demands precise throttle control and maximum traction. This makes it an ideal choice for tight woods, rocky trails, and technical enduro courses where bottom-end grunt is more valuable than top-end rpm.
