ECS Tuning R5X Performance Cat-Back Exhaust

Engineered with precision and crafted for enthusiasts, our ECS Tuning Cat-Back Exhaust System for the MINI Cooper S and JCW delivers a true blend of performance, aesthetics, and acoustic refinement. Whether you’re carving corners or cruising the highway, this system transforms your MINI’s character while maintaining real-world usability.

From the first drive, the system delivers a distinctly refined but sporty soundtrack. In non-sport mode, it produces a deep, bass-heavy tone that’s civil around town. Switch into sport mode, and the sound comes alive with pops and burbles that add excitement without overwhelming the cabin. Highway drone is kept to a minimum.

*Car was driven with engine not fully warmed up and NOT in sport mode*

When car is warm and in sport mode you will hear more of the factory pops and bangs from the exhaust. This is more notable on the 2007-2010 MINI Cooper S. 2011+ MINI Cooper S, the pops and bangs are more muted from the factory. On all factory JCW cars the pops and bangs in sport mode are more elevated.
