High-Performance Exhaust Upgrade Enhance the performance and aesthetics of your CFMOTO 450SR with Vandemon’s high-mount exhaust system. Constructed with polished 304 stainless steel headers and dual mufflers, this system removes the restrictive catalytic converter, unlocking significant gains in mid-range torque and horsepower. The high-mounted design retains passenger footpeg compatibility and features removable silencers, allowing riders to adjust sound levels to their preference. However, the exhaust may not comply with international noise regulations—please consider this before purchasing.

Enhanced Appearance The exhaust system is polished to a mirror-like finish, ensuring long-lasting shine and minimal maintenance compared to lower-grade stainless steels. Each system includes carbon fibre covers, adding a sleek, race-inspired touch to your CFMOTO 450SR.

Installation Note Minor modification required: To fit the rear up-pipe without interference, a small section of the rear hugger must be trimmed. Detailed instructions are provided for this simple adjustment. Tuning Recommendations The included silencers allow for operation without an ECU remap, as any minor fueling adjustments are managed by the OEM mapping. However, for maximum performance—especially when silencers are removed—professional tuning and a DNA air filter are recommended to optimize the air/fuel ratio.
