I don't get the whole airbag thing with bull bars. The ARB will reinforce the frame horn crumple area and an impact will transmit a stronger crash pulse to the body where the sensor is under the console, but that will only make the airbags more likely to fire than less. The sensor is located near the occupants for a reason, so it will read the impact as it relates to how the occupants would experience it, and will fire the airbags accordingly.
