Drawing on over 35 years of racing heritage, the FMF Racing Fatty Gold Series exhaust pipe is engineered for riders seeking broad, smooth power gains across the entire rev range. Designed using FMF?s proprietary Tru-Flo stamping process, this pipe enhances throttle response, widens the powerband, and provides seamless performance improvements?from low-end grunt to top-end over-rev. Built from carbon steel with a durable nickel-plated finish, the Fatty is compatible with both FMF and stock silencers and is recognised as FMF?s most popular 2-stroke pipe.
