The FMF Factory 4.1 RCT Slip-On Exhaust Muffler is designed for the Kawasaki KX250F (2025-2026) and KX250X (2025-2026).

Constructed with a gray anodized aluminum muffler body, stainless steel mid-pipe, and carbon fiber end cap, it offers an excellent balance of lightweight performance and durability. The exhaust also incorporates the Rapid Tuning System (RTS) for optimized performance and includes a removable screen-type spark arrestor.
