Cobra Sport Valved Quad Exit Cat Back Exhaust (M3 Style) - BMW F40 M135i

This Cobra Sport valved cat back system replaces the PPF, centre and rear sections of the F40 M135i with 3" (76.2mm) pipework and converts it to an M3-style quad exit layout. The factory valve is retained, so you keep a calmer tone for cruising and a much louder one in the sportier drive modes.

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. An M3-style quad exit rear valance panel is required and is not included. Valved versions retain the factory exhaust valves, so the tone still changes between quieter and louder settings as you switch drive modes.
