FMF Factory 4.1 RCT Slip-On Exhaust with Stainless Steel Mid-Pipe and Carbon Fiber End Cap, Part 045713

Upgrade your 2026 Ducati Desmo450 MX or 2026 Ducati Desmo450 EDX with the FMF Factory 4.1 RCT Slip-On Exhaust. Manufacturer part number 045713, this tuned exhaust system uses FMF Resonance Chamber Technology to help reduce sound levels while maintaining strong power output. The stainless steel mid-pipe is paired with a durable carbon fiber end cap for a performance-focused design suited to demanding motocross and off-road riding.

FMF’s patented core shape helps control exhaust sound without restricting the engine’s power potential, while the patented canister shape provides additional internal volume for sound-absorbing material. The refined chamber design is engineered to improve exhaust pressure characteristics for application-specific performance. Factory Forward Engineering centralizes mass and helps reduce vulnerability to crash damage, making this slip-on a practical choice for competition and trail environments.

Installation is simplified by the innovative rear end cap, which accommodates tuning tip inserts or a spark arrestor. The exhaust includes a spark arrestor and wash plug for added convenience during maintenance and off-road use.
