Has to be a coincidence. Say you get a DINAN exhaust, which is endorsed by BMW and is covered under their manufacturer warranty. The DINAN exhaust has NO actuator flap and does not control which pipe exhaust comes out of. The actuator is mostly a sound dampener and slightly warms the cats up faster. After that the actuator is mostly for sound. Just my .02 but ready with firesuit.
