Milltek Cat-back - Non-resonated (louder) - Mk1 - (R52) Cooper S Convertible - 2004-2008 - SSXM403
Mandrel bending ensures constant radius bends for optimised gasflow, and bore diameters are carefully enlarged over stock to ensure ultimate without the loss of mid-range torque. All of the Milltek exhaust systems endure a comprehensive acoustic development process to deliver a tone that is sporty and crisp, without ever inducing NVH, drone or cabin resonance.
