Toyota GR Yaris - Sport Exhaust with Sound Architect™ (2020 on) - QuickSilver Exhausts

Toyota GR Yaris - Sport Exhaust with Sound Architect™ (2020 on)




Quiet or Loud - at the touch of a button.

In Loud, the QuickSilver Sports exhaust delivers a Group B experience. And we should know, having owned Group B cars in their heyday - in particular our Renault 5 Turbo 'Tour de Corse' and Peugeot 205 T16 'EVO'.

In Quiet, our system has a sound similar to OE, so in-town drivers need not upset their neighbours.

Installation could not be easier - the 'Sound Architect' module simply plugs into the cigarette-lighter socket and operates wirelessly using the QuickSilver 'Sound Architect' APP. There is no intrusion into the car's original systems and it is just as easily removed (on resale?). There are no warranty or emissions consequences.

The QuickSilver system is manufactured using T304 austenitic Stainless Steel and 70mm tube. Full-bore mandrel-bending ensures optimum gas flow.



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'.

Appropriate sound - 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.
