LR391S - Land Rover Defender P300 90/110/130 - Sport System with Sound Architect™ (2021+)

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.
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.  

Installation service can be provided, contact info@projectrebel.co.uk

While the majority of our products are accompanied by instructions, certain items are inherently intricate and may not include accompanying literature. This is standard practice within our industry, emphasising the importance of seeking professional assistance to ensure proper bonding of such products.

Unless otherwise stated, our products are engineered to facilitate installation without the need for drilling or altering any part of your vehicle. Should you require any assistance, please don't hesitate to reach out to us, and be sure to explore our installation service for added convenience and peace of mind.

Dispatch times

We normally dispatch processed orders next working day on a 24 hour courier service. Some areas of the UK are not covered by a 24 hour service (please see postcode list above), in this instance we will endeavour to use the next fastest service available. Any references to "24 hour" or "next day" delivery services exclude weekends or UK bank holidays.

We use an automated service to provide prices for international delivery, in some cases a given combination of products may result in a higher than expected shipping cost. In this instance, we will contact you to discuss the options prior to shipping the order. Shipping times will vary depending on the delivery country, and a number of external factors. We will not guarantee international delivery times, or be held liable for any damage or loss caused by delays in shipping.

We will generally select the best shipping method as a compromise between cost and delivery times; if you have a need for expedited (or economy) delivery, please make a note on the order or get in touch before placing the order.

Tariffs, Taxes, and Duties

If you are ordering from outside the UK, you may have to pay additional charges to import the goods into your country. Different countries apply different charges at different thresholds - you can check your country's rates via your Government or Tax office website. Payment of these charges is the responsibility of the importer (buyer) of the goods, and will be paid to your local Government or Tax office.
