One of the main draws of the 2023 Corvette Z06, in addition to its blistering performance and head-turning looks, is the exhaust note. With a new dual overhead camshaft, flat-plane crank 5.5L LT6 V8 engine, the latest iteration of the Corvette Z06 trades the traditional roar of a Small Block for a refined purr that sounds more like a high-priced foreign exotic.
Chevy recently released a video, appropriately titled ‘A Glorious Exhaust Note’, explaining how the Corvette Z06 engineering team worked hard to ensure the mid-engine performance car had the kind of exhaust note that was befitting of a world-beating mid-engine supercar such as this. The clip features commentary from one of the people responsible for this head-turning exhaust sound, Cindy Molnar, who serves as a vehicle performance engineer for the Chevrolet performance car division.
“One of the things with the Z06 is we wanted to make sure that the feel of the car from a vibration standpoint, and the sound that you’re hearing, just gives you the feeling of being in this exotic car, and the feeling of something you’ll never be able to forget,” Molnar said of the LT5’s high-pitched exhaust. “The sound of the Z06 is incredible. The first time I heard it with the production exhaust, I got goosebumps.”
As some Corvette fans will already know, the Corvette Z06 can adjust its exhaust sound on the fly thanks to its intake manifold valves and variable exhaust valves. The exhaust valves are particularly impressive, capable of adjusting at two-degree increments to make small, minute changes to the exhaust note. While previous Corvette models had exhaust valves, they only had two settings: open or closed. “We always had that mild to wild feel,” Molnar added. “Now we can tune it and finesse it and get the exact sound we want at every RPM and in every mode.”
