Description
The FMF Factory 4.1 RCT Exhaust System features advanced FMF Resonance Chamber Technology™ both internally and externally for optimal power delivery and sound control. Designed for the 2022-2024 Honda CRF250R, this system uses aerospace-grade titanium for the main pipe and a blue anodized titanium muffler with a carbon fiber end cap. The shorter overall length reduces crash damage risk and centralizes mass for improved handling. The system incorporates Factory Forward Engineering, rapid tuning, and comes complete with a Titanium Megabomb header for increased power across the RPM range. Manufactured in the USA, this system is built for riders seeking maximum performance and weight savings.
