Land Rover Defender P400 90, 110 OR 130 - Sport System with Sound Architect™ (2021 on)

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 our new standalone key fob - 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.  

 Sound Architect® Remote Valve Control by QuickSilver

The new QS Sound Architect® remote valve control system gives you full command of the sound. Our push-button fob can be mounted within the vehicle or used outside the vehicle if desired.

Its binary functionality offers two distinct sounds to suit your environment. Our default ‘Sport’ mode offers the full experience with a deeper robust note and utilises the optimum flow of the exiting exhaust gases. With our ‘Refined’ mode, our exhaust harnesses the tone, offering a more civilised note when, and if it’s required.

Even better is that like our exhausts, this is a simple install. Just feed the valve cables through the spare wheel well to the rear section, plug the power cable into the 12v in the boot, and you’re away!

This style of valve control’s been requested a lot in the past, and we’re excited to finally offer this – the perfect sound is now just a button press away.
