Land Rover Defender Octa 110 P635 Quicksilver Edition – 2025+ with Sound Architect System

Description

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.
