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 new QuickSilver wireless key fob. 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, and perfect sound. 

 Sound Architect® Remote Valve Control by QuickSilver

The new QS Sound Architect® remote valve control system gives you full command of the sound. Our push-button fob can be mounted within the vehicle or used outside the vehicle if desired.

Its binary functionality offers two distinct sounds to suit your environment. Our default ‘Sport’ mode offers the full experience with a deeper robust note and utilises the optimum flow of the exiting exhaust gases. With our ‘Refined’ mode, our exhaust harnesses the tone, offering a more civilised note when, and if it’s required.

Even better is that like our exhausts, this is a simple install. Just feed the valve cables through the spare wheel well to the rear section, plug the power cable into the 12v in the boot, and you’re away!

This style of valve control’s been requested a lot in the past, and we’re excited to finally offer this – the perfect sound is now just a button press away.

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.
