Lamborghini Aventador LP700 - Sport Exhaust with Sound Architect™ (2011 on)




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.


The original exhaust has a clever internal design with tube-lengths, diameters and chamber volumes that produce a range of notes. 

The QuickSilver system improves on this with an even greater range (deeper low down and higher at the top end)  amplified and sharpened to provide the occupants with a dramatic performance that brings howls and smiles.
