In Sept 2018 the new WLTP (World harmonised Light vehicles Test Procedure) was imposed as a result of the VW emissions cheating scandal.
The WLTP rules compel all car manufacturers to ensure that their vehicles comply rigidly with worldwide harmonised noise regulations. The practical result is that cars manufactured after this date are significantly quieter. And... the simultaneous imposition of particulate filters makes them quieter still.

For many citizens this is desirable, but for enthusiast drivers the sound is an important element of the experience and almost no one wants a silent Sports Car (even electric vehicles are being saddled with artificial soundtracks).
The QuickSilver 'Sound Architect exhaust for the Yaris GR should please all enthusiasts with it's bass-heavy presence and rising note under acceleration - With nice turbo wheezes, even Tommi Mäkinen would be satisfied.

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, the Porsche GT3 and Audi R8 are fully integrated.

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.
