The new mountune EC Approved Cat Back Exhaust for the Mk3 Focus RS is the result of countless hours of engineering and ongoing product development, offering a product that is simply unrivaled in terms of performance, sound and features.

Extensive effort was placed on producing a sound profile that replicated the personality of the RS, with an aggressive note under full throttle, while maintaining a drone-free experience during cruising and light throttle.
