The QuickSilver Sport System with Sound Architect Valves gives your Defender P300 the sound you expected from the factory. Loud or Quiet – our system uses our revolutionary Sound Architectâ„¢ 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 inline six car sound that enriches the experience. Furthermore, in dynamic driving mode on occasion the exhaust delivers wonderful pops 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 if ever required.
