Question Electronics to detect M mode enabled/disabled?

How would one go about hooking into the car's electronics to detect when the M button is enabled or disabled?

Basically I want to open my exhaust cutouts whenever M mode is turned on. I have the electronics experience to rig up a microcontroller and relay to trigger the cutouts, but I don't know how to detect when M mode is enabled.

Maybe some signal on the CAN bus? I have no idea.

Avoiding anything warrenty-voiding would be nice.

Thanks.

the6M3 from the thread referenced above has the right idea:
