Corsa Active Valve Technology:

Over two years of research went into developing a Corsa active valve exhaust system that would deliver the ultimate driving experience: a varying range of volume combined with No Drone RSC® Technology. The valves need to perform under various conditions; after testing many off-the-shelf valve solutions, a Corsa valve was built and torture tested in order to deliver the desired quality. It was subjected to intense heat cycling conditions and yielded no failures at well over half a million cycles. Corsa active valve technology meshes seamlessly into the Mustang GT valve operating system by maintaining the factory solenoids to ensure flawless functionality

The Corsa Active Valve, combined with RSC® Technology, is more effective than the stock system at providing a comfortable drone-free cruise. Utilize the quiet start function or run wide open; Corsa Active Valves produce an impressive 11 decibel delta in volume across the various driving modes.
