Milltek Active Valve Control for BMW 2 Series M240i Coupé (G42 XDrive - NAS Non OPF/GPF Models Only) (2022 onwards) – Switchable Exhaust Volume
This is Milltek's active valve control system for the BMW 4 Series G22 M440i Coupe (OPF/GPF Equipped Models Only) Pre LCI. 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.
