FMF Factory 4.1 RCT Titanium Slip-On Exhaust with Megabomb for Kawasaki KX450F and KX450X, Part 042404

The FMF Factory 4.1 RCT Titanium Slip-On Exhaust with Titanium Megabomb is engineered for Kawasaki motocross and cross-country applications. This tuned exhaust system is designed to fit the 2024, 2025, and 2026 Kawasaki KX450F and KX450X. FMF part number 042404 delivers application-specific core specifications to help optimize power output while maintaining a refined exhaust note.

Built with FMF’s latest Resonance Chamber Technology, the exhaust uses a patented core shape to reduce sound levels without sacrificing performance. The patented canister shape increases internal volume for additional sound-absorbing material, while the chamber design helps enhance and refine exhaust pressure. Factory Forward Engineering centralizes the exhaust mass, helping reduce the likelihood of crash damage and supporting a more practical installation on the motorcycle.

The included Titanium Megabomb is designed to optimize power delivery for the Kawasaki KX450F and KX450X. An innovative rear endcap allows straightforward installation of tuning tip inserts or a spark arrestor, giving riders flexibility for different riding environments and requirements. The FMF Factory 4.1 RCT system combines titanium construction, tuned performance, and fitment-specific engineering in a direct-fit slip-on exhaust solution.
