The FMF Gnarly expansion chamber is engineered specifically for off-road riders who demand maximum low-end torque and throttle response. Designed for the Kawasaki KX500 from 1988 to 2004, this pipe transforms power delivery by focusing on bottom-end grunt where technical terrain demands instant power.

• Electro-nickel plated finish resists chipping and discoloration for long-lasting appearance
• Optimized for maximum low-end power boost and torque delivery
• Designed specifically for 200cc and larger displacement engines
