Akrapovic Downpipe without Cat - M2 (F87) - 2016-2017
The next step in the exhaust-tuning process is the addition of a stainless-steel downpipe without a catalytic converter.
This will provide the best sound optimisation and increase the performance of the car. Designed primarily for track use, the ECU will need to be remapped when this downpipe is fitted to the Evolution Line exhaust system.
The use of de-cats, sports cats are for off road/motorsport use only. Using these parts would inhibit your vehicle from passing a MOT test.
Only EC type-approved components are legal and fit for road use.
