Milltek ValveSonic + for BMW 1 Series M135i 3 & 5 Door (F21 & F20, Non-xDrive) (2012-2016) – Switchable Exhaust Volume
This is Milltek's ValveSonic system for the Milltek Sport Products ValveSonic + BMW F Series Models. It adds Milltek's electronically-operated valve to the system, opening a less restrictive path through the silencer that stays closed for a refined, near-standard tone and opens under load or on demand for a louder, more open sound.
It's the option to go for if you want the flexibility to keep the car quiet day to day and switch to the full exhaust note whenever you actually want to hear it.
