Description

The Red Rooster Rumbler is a performance-oriented slip-on exhaust developed for Royal Enfield’s classic UCE platforms. It is designed to deliver a deeper, fuller exhaust note while maintaining everyday rideability and long-distance reliability.

Manufactured from SS304 stainless steel, the Rumbler prioritizes corrosion resistance and structural longevity. Unlike conventional exhausts that rely on glass wool, this unit uses ceramic wool packing, offering superior heat tolerance and slower sound degradation over time. The exhaust note remains consistent across extended usage, highway runs, and varying thermal conditions.

The internal flow design is tuned to reduce exhaust restriction compared to the stock muffler, supporting improved throttle response and freer engine breathing. Red Rooster claims modest performance gains when used on an otherwise stock motorcycle, without requiring ECU remapping or engine modifications.

The Rumbler is a bolt-on replacement that mounts directly to factory exhaust points, preserving serviceability and stock alignment. Multiple finish options are available and selectable as variants.
