Show original supplier description
The Milltek SSXM436 is a performance-oriented cat-back exhaust system specifically designed for the 2014-2018 Mini Cooper S 2.0 Turbo (F56, UK and European models, pre-facelift). This system is non-resonated, offering a louder, sportier exhaust note. Constructed from aerospace-grade type 304, non-magnetic stainless steel, this exhaust is built for longevity and resistance to discoloration. It features 2.75-inch (69.85mm) pipework with mandrel bends for optimized gasflow and enlarged bore diameters to enhance performance without sacrificing mid-range torque. The system includes twin 90mm GT90 tips finished in Cerakote black and incorporates Bluetooth valve control, allowing the driver to adjust the exhaust sound profile. Installation is estimated to take 1.5 to 2 hours. This system is noted as a 'Race System' and is not EC Approved, indicating it is intended for off-road or motorsport use and may not be legal for road use in all regions.
