Fatty Exhaust Pipe 93-97 Yamaha 250 WR YZ - FMF 020137

The Fatty Gold Series pipe by FMF Racing is the result of more than three decades of racing development, engineered to deliver race-proven performance and broaden the usable power curve. This expansion chamber boosts power across the entire rev range, enhancing throttle control and providing both increased low-end torque and strong top-end over-rev. Constructed from durable carbon steel with a nickel-plated finish, the Fatty is designed to withstand rigorous conditions and is compatible with either FMF or original silencers for versatile installation.
