Milltek Active Valve Control for Audi RS4 B9 2.9 V6 Turbo Avant (Non OPF/GPF Models) (2018 onwards) – Switchable Exhaust Volume
This is Milltek's active valve control system for the Audi RS5 B9 2.9 V6 Turbo Sportback (Non-OPF/GPF Models). 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.
