Electronic/Pneumatic Valves - Retains OEM (in-car) functionality

Our active valve sport exhaust systems contain two separate gas paths, and an electronic or pneumatic flap-valve that decides which path is taken. Both have two distinct levels of sound and are slightly louder than stock. With the valves closed, the system takes on a more civilised note and when they’re open, you’re given a sporty note throughout the rev range.

These valves are integrated into the car’s existing controls and function depending on the ECU mapping. This can then be further manipulated either with the dedicated exhaust button or by switching the driving modes.




A full manifold back system which includes sports catalysts. The system reduces crucial weight from the rear end of the whilst improving the flow for the exiting exhaust gases. This shows a noticeable improvement all round performance and throttle response whilst enhancing the sound throughout the rev range.
