The new F90 M5 does have this characteristic built in from factory, but to my knowledge the F10 M5 does not. The S63TU power units between the F10 M5 and the F12/F13/F06 M6 are exactly the same, including the DME/ECU which would control this sort of thing.
I guess it depends on your definition of 'mild mild' crackle — I have the competition package mufflers on my car with the valves held open by hose clamps, and I notice a very slight, muffled burble when downshifting at low RPM's (for example: manual downshift in 2nd @1,200rpm to 1st in a parking lot with the windows down where the wind noise wouldn't drown it out, that's how subtle it is)
