Chevy Shows Off Corvette Stingray’s Adjustable Exhaust Valves: Video

Follow Viknesh

An adjustable exhaust valve on the new 2014 Chevrolet Corvette Stingray means the car can have a split ‘Jekyll and Hyde’ personality. Driving around town valves located inside the car’s exhaust pipes sit shut to mute the sound and keep things civil. When the driver wants, however, these valves can be opened to let the full fury of the Corvette Stingray’s LT1 V-8 engine be heard.

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.
