CFMOTO 450SR-S Stainless Steel Exhaust System 2025-2026

Performance-Driven High-Mount Design

Engineered exclusively for the single-sided swingarm 450SR-S model (2025), this stainless steel exhaust system delivers a powerful combination of performance, sound, and aesthetics. Featuring polished 304 stainless steel headers, a resonated mid-pipe, and twin stainless steel mufflers with removable silencers, this system ensures you retain passenger foot peg functionality while achieving superior results on the road or track.

By eliminating the catalytic converter, this exhaust system significantly enhances mid-range torque and horsepower. The result is a thrilling sound profile reminiscent of a V2 Ducati and a stylish upgrade from the original exhaust system.

Included in this package is a Number Plate Tail Tidy for a clean, streamlined appearance.

INSTALLATION NOTES

Minor modification required: A small portion of the rear hugger must be trimmed to provide clearance for the rear up-pipe. Detailed instructions and visuals are included to simplify this adjustment.
