The FMF Factory 4.1 RCT Anodized Titanium Slip-On Exhaust is engineered for Honda CRF450X models from 2019 through 2026. Manufacturer part number 041587, this FMF exhaust uses Resonance Chamber Technology to reduce sound levels while maintaining strong power output. Its tuned core specifications are optimized for the application, helping refine exhaust pressure and deliver consistent performance across demanding off-road conditions.
The patented canister shape increases internal volume for additional sound-absorbing material, while the patented chamber design enhances exhaust flow and pressure control. Factory Forward Engineering centralizes mass for improved handling and helps reduce the likelihood of crash damage. The titanium canister and mid-pipe provide a lightweight, durable construction suited to trail and competition use.
Installation is simplified by the innovative rear end cap, which supports tuning tip inserts or a spark arrestor. The exhaust includes a spark arrestor and wash plug for convenient trail maintenance and off-road compliance. This FMF Factory 4.1 RCT slip-on fits 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026 Honda CRF450X motorcycles.
