SOUND ARCHITECT™ 

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.


DETAILS 

QuickSilver's Cullinan Exhaust takes the Cullinan from silent to sporty with a defined V12 soundtrack.

QuickSilver's Titan Exhaust is a titanium / stainless hybrid; with the lightweight titanium silencer producing a warm resonance, favouring transients in the upper formant. The 3" stainless tubing provides the powerful low end punch. The combination produces a sports exhaust with a fantastic dynamic range.

QuickSilver's Sound Architect valves add the finishing touch, allowing the owner to switch the valves 100% open or closed at the touch of our bluetooth app.
