What it does

About this part

This active valve system allows the driver to switch from a refined tone to crazy race car loud in an instant and comes with our special carbon sleeved tips to define the look.

QuickSilver's Sound Architect exhaust system contains two separate gas paths and an electronic flap-valve decides which path is taken, loud or quiet. This valve is controlled by the QuickSilver APP on the driver's telephone or (in many cases) integrated into the car's existing controls, the Porsche GT3 and Audi R8 are fully integrated.

The full story

About Quicksilver

QuickSilver was founded in London in 1973. At this time, the average life expectancy of the original exhaust system was only 18 months. There was a demand for something better… So QuickSilver created exhausts from Stainless Steel that would last the life of the car. Now, they produce superior exhaust systems for the World’s finest cars that are lighter, stronger, more efficient and enable personalisation.
