It is supposed to trick the system into thinking the Active Exhaust is operating normally but the valves are always open, and there is no check engine light. The MDS feature on the automatic will still be operational, but Sport Mode disables the MDS, as does pulling the auto stick towards you into manual while cruising.

IMO it looks like the smartest solution yet to the Active Exhaust and keeps your stock parts in place in case you need to convert it back. Ry
