The new mountune EC Approved Cat Back Exhaust and now Non Resonated option 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.
