Land Rover Defender OCTA 110 P635 Quicksilver with Sound Architect (2025 on)
The QuickSilver Sport System with Sound Architect™ is a performance and sound upgrade for the Defender OCTA with its 4.4L twin-turbo V8.
You control the sound using the QuickSilver app on your phone. With the valves closed, the exhaust stays quiet and subtle - ideal for long drives or early mornings. Open the valves, and the V8 comes to life with a deeper, louder tone.
In OCTA mode, you also get pops and crackles on upshifts and overrun.
The system is plug-and-play. It doesn’t touch the factory setup and can be removed anytime.
KEY FEATURES
• Valve control for the perfect sound.
• Stainless Steel mandrel bent tubing.
• Improved throttle response.
• Fantastic burbles, crackles and pops on the overrun.
• Civilised to Muscle car in an instant.
• Retains the unique OCTA tail pipe finishers to keep the look
