The system fits the 2014 on model. 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

 

SOUND ARCHITECT

Electronic Valves inc. Sound Architect™ Module - uses QS APP (Android and iOS)

Our Sound Architect App hands control of the valves back to the driver for the ultimate experience. When you select ‘Open’ they’ll stay open and when you select ‘Closed’ they’ll stay closed – this choice will be remembered even after the car’s been turned off and on. 

The electronic module included only requires a 12v feed, usually a cigarette-lighter socket. It’s Bluetooth controlled on the driver’s smart device, and pairing takes just a minute.

The electronics are designed in-house and manufactured for us here in the UK, using local British factories

Origins & Experience - Since 1973

QuickSilver was founded in 1973, originally in Esher, Surrey. At this time the average life expectancy of an original equipment exhaust system was only 18 months > There was a demand for something better!

QuickSilver settled down in Battersea, central London from 1985 to 2003.

In 2004 QuickSilver's marketing and distribution moved to new purpose -built premises in Wormley, Surrey, to focus on the creation of a modern QuickSilver range of systems for the world's finest cars.

Systems - Manufactured in Great Britain - Exhausts are Custom Order and can take 4-6 weeks for production. Please contact GMP for details.

QuickSilver's range breaks down into three main categories;

Sports: The most popular range of systems catering for modern cars enhancing their sound and overall performance. QuickSilver offer a choice of sound for many vehicle models to allow the enthusiast driver to personalise the experience.

Heritage Collection: A 3000 plus catalogue of systems dating back to 1902, supplying Stainless Steel systems that match the original. For over 35 years QuickSilver have produced and stocked systems for the likes of MGB, Jaguar XK120, Alfa Giulia, Aston Martin, Ferrari – all the popular Classics and this is still a very important part of QuickSilvers's business.

Titan Collection: A bespoke service where QuickSilver strive to engineer the ultimate Exhaust systems. The exhausts included within the 'Titan Collection' are systems that have all the advantages of the 'Sports' range but QuickSilver have examined ways to reduce weight to a minimum by using alternative materials such as thin gauge stainless steel (.9mm), Titanium or Inconel in .7 or .9mm thickness. Some systems combine these materials to achieve the correct balance of strength, lightness and durability.

Global Identity

QuickSilver distribute through a worldwide network of dealers who enjoy a wealth of marketing material and joint promotion via shared advertising and QuickSilver's participation in local events. This is backed by QuickSilver's sponsorship of individual competitors from national rallying to international endurance racing.
