Cobra Sport Turbo Back Exhaust - BMW F40 M135i

This Cobra Sport turbo back system replaces the front pipe, centre and rear sections of the F40 M135i with 3" (76.2mm) stainless steel pipework, transforming the muted factory sound and opening up further tuning potential. It keeps a rear silencer and can be configured with a sports cat or de-cat front pipe, resonated or non-resonated centre section, valved or non-valved, and 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. De-cat versions are for motorsport / off-road use only. Sports cat versions replace a factory emissions device, are not EC homologated and may not meet emissions laws for road use. 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.
