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
