Custom Code v7.1 introduces the ability to control electronic Exhaust Flaps On-The-Fly, to open, to close and to return to OEM functionality. This feature is controls the flap in real-time, prior to accepting the flap status, you can sample it (hear how the exhaust sounds while open and closed). Safety has been added via load limiter. Once the load limit is exceeded, the exhaust flap automatically opens to allow additional air to flow and reduce exhaust pressure.
