It's not removable...it's part of the grill itself. I assume it's there to provide more rigidity and stability for the TSS sensor.
I also don't like the idea of the sensor blocking a full width lightbar. The best solution would be two individual lights or bars either side of the sensor with nothing behind it, but nobody really makes a complete kit at this time to the best of my knowledge.
The best solution I've been able to find is the N-Fab mount which would allow mounting whatever lights you wanted either side of the sensor.
