Alfa Romeo 4c Coupe and Spider - Sport Exhaust System w/ Sound Archite - QuickSilver Exhausts


Alfa Romeo 4c Coupe and Spider - Sport Exhaust System w/ Sound Architect APP (2014-19)

Alfa Romeo



Our industry leading 'Sound Architect' active valved exhaust system contains two separate gas paths and an electronic flap-valve decides which path is taken, loud or quieter. 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 this system we analysed the sound of the 4C to determine which elements should be suppressed and which enhanced. 

This system is also 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.



Made from genuine carbon fibre with a matt finish, these branded tailpipes offer your Golf R a unique look over stock and fill the rear valance perfectly.
