As Patrick Herrmann, the Corvette’s technical communications manager in Europe, explains in the video above, the valves are adjusted by an electric motor instead of a vacuum solenoid, as was the case for previous Corvettes. Switching the car into Sport or Track modes via the Driver Mode Selector dial on the dash opens up the valves.
After watching, we’re sure you’ll agree there is a significant difference in sound when the valve is closed and when it is opened.
