Quick Silver BMW M240i Sound Architect Titan Sport Exhaust (2017 on)

  • Sale
  • Regular price £1,580.00
Tax included.



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.


QuickSilver's Sound Architect exhaust system contains two separate gas paths and an electronic flap-valve decides which path is taken, loud or quiet. This valve is controlled by the QuickSilver APP on the driver's telephone or (in many cases) integrated into the car's existing controls, the Porsche GT3 and Audi R8 are fully integrated.

In creating their system QuickSilver analyse the sound of the modern car to determine which elements should be suppressed and which enhanced. 

The valved QuickSilver Sound Architect systems are truly 'plug & play'. The electronic module simply connects to an existing accessory socket and is controlled wirelessly - so there in no intrusion into any of the car's existing systems and no re-wiring is necessary. It could not be simpler.

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