This package removes the restrictive factory primary catalytic converters and is a great ‘bang for buck’ upgrade. The downpipes add aural drama to the mix while keeping everything looking stock from the outside and under the bonnet. All Hack Engineering tuning packages come with the added security of a Koflach Engine Developments Crank Hub Capture Plate. Outputs of approximately 550bhp and 750nm of torque on premium fuel (97+ octane). Factory figures of 425bhp and 550nm (original M3/M4).

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only. Sports cat options available by request. For models equipped with an OPF, the pressure monitoring will be deleted and so we also recommend having an OPF delete fitted at the same time. Contact us for options and details.
