Land Rover Defender P525, P425 V8 90, 110 OR 130 – SPORT System with Sound Architect™ (2021 on)

Loud or Quiet – our system uses our revolutionary Sound Architect Module, which is controlled by your mobile phone via the QuickSilver App. It could not be easier.
With the valves shut the QuickSilver system provides a civilised note which is unobtrusive and perfect for long journeys and early starts.

Switch to valves open and the monstrous side comes alive with volume and pitch increased to deliver a pure muscle car sound that enriches the experience.

Furthermore, in dynamic driving mode all the pops, crackles and bangs are present on the up-change & overrun, a nice touch.

The QuickSilver system is truly plug & play, it requires no intrusion into the cars’s OE systems and is completely reversible (on resale?).

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.
