Quicksilver BMW M4 (F82 / F83) Sport Exhaust with Sound Architect Valved (2014 on)
QUICKSILVER EXHAUSTS
Our 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 our QuickSilver APP on the driver's bluetooth device or (in many cases) integrated into the car's existing controls.
We analyse the sound of the car to determine which elements should be suppressed and which enhanced.
Our valved QuickSilver Sound Architect systems are also truly 'plug & play'. If the the electronic module is required it simply connects to an existing 12v 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.
