Cobra Sport Cat Back Exhaust - BMW F40 M135i

This Cobra Sport cat back system replaces the PPF, centre and rear sections of the F40 M135i with 3" (76.2mm) stainless steel pipework, bringing out far more character from the B48 while keeping a rear silencer. Configure it resonated or non-resonated, valved or non-valved, with a choice of tailpipes.

Please note: This system removes the PPF (petrol particulate filter) and is sold for motorsport / off-road use only. Engine tuning (ECU remap) is required at the time of fitting to cancel the EML light. Valved versions retain the factory exhaust valves, so the tone still changes between quieter and louder settings as you switch drive modes. Non-valved versions remove the exhaust valves, so the sound will no longer change with drive modes. This will not harm the running of the car.
