F56 Hardtop & F57 Convertible B48 engine

John Cooper Works Tuning Kit for the B48 Engine with 'dual mode' selectable exhaust from MINI adds performance and maintains your factory warranty! Dual mode exhaust switches between 'street mode' and 'track mode' using a battery powered remote. The 'track mode' is pretty much a straight pipe that bypasses the muffler for incredible sounds with pops and burbles!

Exhaust tips are NOT INCLUDED in this kit and must be ordered separately.

You will need to have a MINI dealership or other qualified shop install the JCW ECU software to activate this exhaust.

Include the last 7-Digits of the VIN number when ordering.


  • A stainless steel cat-back system – cannot be sold without the engine kit
  • Optional Carbon Fiber and Stainless tips with JCW logos
  • 15hp Power increase due to ECU remapping and increase flow
  • A remote that allows the driver to open and close the electronic baffle inside the exhaust allowing for a more aggressive note when appropriate
  • Track mode – opens the exhaust baffle increasing exhaust noise via a button on the remote (this is mode is not approved for the street)

The Kit is different depending on the engine type in your MINI.  Early F56 models had the B48 engine (some 2014 models) and later models have the B46 engine.

Fits the following models with the B48 engine:

2014 F56 MINI Cooper S Hardtop

NOT for models with the S3ARA Luggage Carrier Option.

Select the Tuning Kit, and one of two types of Exhaust Tips.

Remotely activated exhaust valve:

B46 vs B48 Engines

The initial 3rd Generation F56 MINI Cooper S Hardtop models were introduced with the B48 engine from BMW for the 2014 model year.  The B46 engine replaces the B48 with the 2015 model year. The B46 is a variation of the B48 but classified as Super Ultra Low Emissions Vehicle (SULEV) by the EPA.  Both engines are rated at the same horsepower and torque, but the B46 should have slightly better MPG numbers (unconfirmed).
