Cobra Sport 3 inch Primary De-Cat Downpipe for BMW M3 F80 2014 to 2018. The ultimate catless downpipe upgrade for the S55-powered M3, engineered to increase exhaust flow, sharpen throttle response and unlock performance when paired with a suitable ECU remap. Expect a deeper, more aggressive exhaust note and quicker turbo spool for a harder-hitting power delivery.
We have fitted and run this Cobra Sport de-cat downpipe ourselves and customer feedback has been consistently excellent. It transforms the car’s character with a louder, sportier sound and stronger mid-range urgency while maintaining high build quality and reliable fitment.
