Cobra Sport GPF Back Exhaust - BMW F40 M135i

This Cobra Sport GPF back exhaust gives the F40 M135i the sound it should have had from the factory. Built in 3" (76.2mm) stainless pipework, it replaces the centre and rear sections while keeping the standard catalyst and GPF in place.

The system is modular, so it can be extended to a cat back or full turbo back setup later by adding further sections.

Please note: The Valved version retains the factory exhaust valves, so the tone still changes with drive mode. The Non-Valved version removes the valves, so the sound stays the same in every drive mode; this will not harm the running of the car. All fittings and gaskets are supplied.
