Enhance your off-road riding experience with the FMF Factory 4.1 RCT Slip-On Muffler, designed specifically for 2025 and 2026 Honda CRF250R and CRF250RX models. This exhaust system features innovative Resonance Chamber Technology that reduces sound levels while delivering maximum power output, ensuring a balanced combination of performance and sound. The patented core shape optimizes exhaust flow and enhances engine efficiency, while the canister's increased internal volume improves sound absorption for a cleaner, more refined exhaust note. The chamber design is engineered to refine exhaust pressure, providing a noticeable boost in throttle response and overall engine performance.

Constructed with high-quality materials, the FMF Factory 4.1 RCT offers options in titanium or aluminum canisters paired with stainless steel mid-pipes, catering to different durability and weight preferences. The titanium version provides a lightweight solution, ideal for competitive off-road riding, while the aluminum version offers increased durability without sacrificing performance. The exhaust includes a spark arrestor and wash plug for versatile off-road use and compliance with local regulations. The innovative rear end cap allows easy installation of tuning tip inserts or spark arrestors, giving riders customization options to optimize sound and performance further.

Designed with factory engineering principles, the FMF Factory 4.1 RCT centralizes mass for better balance and reduces vulnerability to crash damage. The exhaust system is precisely tuned with application-specific core specifications, ensuring optimal performance across different riding conditions. Additionally, the Megabomb headers, the next evolution in powerbomb development, provide substantial power gains across the RPM range. Whether you choose titanium or stainless steel headers, both options deliver the same high performance with different durability profiles, making this exhaust a versatile upgrade for serious off-road enthusiasts.
