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 Architect™ Module, which is controlled by your mobile phone via the QuickSilver App. It could not be easier.
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.
The QuickSilver system is truly plug & play, it requires no intrusion into the cars's OE systems and is completely reversible if ever required.
• Valve control for the perfect sound.
• Stainless Steel mandrel bent tubing.
• Improved throttle response.
• Fantastic burbles and pops on the overrun.
• Civilised to sports car in an instant.
• The 4 x straight carbon fibre tail pipes and mirrored traverse box are a huge improvement to the rear view.
