Cobra Sport GPF Back Exhaust (Race Box Delete) - BMW F40 M135i

This Cobra Sport GPF back system replaces the centre and rear sections of the F40 M135i with 3" (76.2mm) pipework and deletes the rear silencer, giving a big lift in tone, bass and volume while keeping the factory catalyst and GPF in place. Choose valved or non-valved, with 4" (101.6mm) stainless steel or carbon fibre tailpipes.

Please note: This system has no rear silencer and will be loud. 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.
