Stage6 R/T FL 70 high-end racing exhaust system for Stage6 FL 70cc cylinder kits.

The Stage6 R/T FL 70 exhaust is a high-performance expansion chamber designed for 70cc high-end racing cylinders with FL (Flange Mount) exhaust connections. Developed specifically for the Stage6 R/T FL 70cc cylinder, it is also suitable for other high-performance flange-mount racing cylinders with similar power characteristics.

Featuring carefully optimised resonance geometry, the exhaust is designed to perform at high engine speeds between 14,000 and 15,500rpm. It delivers strong peak power alongside a broad, usable powerband, helping maximise cylinder performance while making engine and CVT tuning easier. The hand-welded construction, curved mid-pipe and carbon silencer complete this dedicated racing exhaust system.
