BMW M240i - Sport Exhaust with Sound Architect™ (2017 on)





A lighter weight system that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound.

The system uses active valve technology allowing the driver to switch from Stealth to Sport using the Sound Architect by QuickSilver.


What is the Sound Architect™?

Have you ever had the need, or want, to turn your Sport exhaust's sound down to a more discreet level? Or, to make it race-car loud - at the touch of a button?

With QuickSilver’s Sound Architect™ we provide you, the driver, with a personal choice – allowing you to select the appropriate soundtrack for your car and tailor that sound to suit the moment.

For your vehicle, we have analysed the sound to determine which elements should be suppressed and enhanced. The result is a superior exhaust note that amplifies the pleasure of driving.

QuickSilver's Sound Architect™ comprises two separate gas paths and an electronic valve to determine which is taken - Sport or Refined. This valve is controlled either by the QuickSilver Sound Architect™ APP, on the driver's smart device, or in many cases integrated into the car's existing controls.

Where appropriate, our sound module connects to an existing accessory socket and is then controlled wirelessly via the Sound Architect™ APP - there in no intrusion into any of the car's existing systems - It could not be simpler.

The QuickSilver Sound Architect™ systems are truly 'plug & play'.
