Show original supplier description

The MINI JCW Tuning Kit is a performance upgrade for B48 and B46 engines, designed to significantly alter your MINI's exhaust sound. Controlled by a wireless remote FOB, this kit allows you to switch between a factory exhaust note and the distinct, aggressive growl of the John Cooper Works system. This comprehensive kit includes a JCW preliminary pipe and rear exhaust with a valved stainless steel muffler, a wireless remote FOB, a tailgate silencer receiver unit, and the necessary wire harness and installation hardware. It also comes with aesthetic JCW badges and certificates for your engine cover and trunk, along with a hood sticker for the underside. In addition to the exhaust components, the kit features an Engine Remap Tune, which provides a 15hp power increase through ECU remapping and improved airflow. For the flap system and engine remap to function correctly, an activation code included in the envelope must be flashed at a MINI dealership. This kit is for the US market only. Buyers will need to purchase 2 x chrome or carbon fiber exhaust tips separately to complete the installation. For MINI vehicles produced between March 2019 and July 2019, a specific update (part ES164380) may be required if the grommet on the main wire harness is too small to seal.
