Milltek Active Valve Control for Land Rover/Range Rover Defender 110 5.0 V8 425PS & 525PS (NAS Non-OPF/GPF Vehicles Only) (2021 onwards) – Switchable Exhaust Volume
This is Milltek's active valve control system for the Land Rover/Range Rover Defender 130 5.0 V8 425PS & 525PS (OPF/GPF Vehicles Only). It adds an electronically-operated valve to an existing Milltek system, opening a second, less restrictive path through the silencer that stays closed for a refined, near-standard tone around town and opens under load or at the press of a button for a louder, more open sound.
It's the option to go for if you want the flexibility to keep the car quiet for early starts and long motorway runs, then switch to the full exhaust note whenever you actually want to hear it, without swapping any hardware.
