The QuickSilver Sport System with Sound Architect Valves gives your Defender P400 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.
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' 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, crackles and pops on the overrun.
- Civilised to sports car in an instant.
- The 4 x straight carbon fibre tailpipes are a huge improvement to the rearview.
