Milltek Sport Downpipe & De-cat Pipe for F56 MINI


Please note this de-cat pipe is designed for motorsport use only and will not pass an MOT. The Milltek Sport large bore downpipe and de-cat pipe replaces the downpipe and catalyst on the MINI F56 Cooper S and JCW. Helps improve air flow and performance whilst creating a louder exhaust growl too.
Cat Back to be fitted with

Manufacturer: Milltek Sport


Replacing the standard downpipe and catalyst in the MINI F56 Cooper S and JCW for the Milltek large bore de-cat downpipe increases gas flow over standard resulting in an increase in horepower and torque. The downpipe and de-cat option is only suitable for track use. 

Fitting the de-cat downpipe requires an ECU tune to code out/reset gas target values the ECU is looking for. Without this the emissions light will be flagged. The downpipe is supplied with an adapter to received either the Milltek large bore cat back or the OE style cat back such as the MINI, JCW or Remus cat back system. Please select from the drop down.
