Designed specifically for the Beta 350 RX, the FMF TurbineCore 2.1 is the world’s best-selling spark arrestor exhaust for a reason. Featuring FMF’s exclusive Turbine Dampening System, it delivers strong, usable power while maintaining U.S. Forest Service approval for legal trail riding.
The straight-through canister design combined with a high-flow stainless steel end cap provides excellent durability and consistent performance without the restriction issues found in insert-style spark arrestors. Built for real-world riding, this silencer performs on both track and trail while offering a clean, factory-level fit on the 350 RX.
