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.
