Milltek Active Valve Control for Audi RS3 Saloon/Sedan 400PS (8V MQB) - Non-OPF/GPF Models (2017 onwards) – Switchable Exhaust Volume
This is Milltek's active valve control system for the Audi TT Mk3 TTRS 2.5TFSI Quattro (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.
