Active exhaust for the RT 5.7 was only added to the +2017 models and that was the year they started using 2.75" exhaust. If you zoom in on the others you can see the active exhaust valves and active exhaust valve simulator. 140627 does not have this which is what you want. Although, you might able to get away with 140715 (not sure if the mid pipes will bolt up to 2.75" pipe) as they just have the AE simulators (bracket that allows AE solenoids to be mounted but does not control an actual valve).
