BMW M4 (F82 F83) - Sport Exhaust with Sound Architect™ (2014 on)




The system fits the 2014 on model. This active valve system allows the driver to switch from a refined tone to crazy race car loud in an instant and comes with our special carbon sleeved tips to define the look.



Electronic Valves inc. Sound Architect™ Module - uses QS APP (Android and iOS)

Our Sound Architect App hands control of the valves back to the driver for the ultimate experience. When you select ‘Open’ they’ll stay open and when you select ‘Closed’ they’ll stay closed – this choice will be remembered even after the car’s been turned off and on.

The electronic module included only requires a 12v feed, usually a cigarette-lighter socket. It’s Bluetooth controlled on the driver’s smart device, and pairing takes just a minute.

The electronics are designed in-house and manufactured for us here in the UK, using local British factories.
