Quicksilver Exhausts BMW M140i – Sport Exhaust with Sound Architectâ„¢ (2016 on) EX-DEMO

This ex-demo system has been very briefly used for demonstrator purposes and was installed and removed by our professional technicians.

Some discolouration to the pipework, light scratching, exhaust paste residue, and inner soot may be present on the pipework and silencer casing.

Tail pipe finishers will be supplied as new.

Electronic Valves inc. Sound Architectâ„¢ 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.
