I have removed and re-installed the front and mid plate, but the rear was dealer-installed and I have not touched it since.
Having probably driven more than most, I can say that I have heard it twice and neither occasion would have caused any damage to the differential (it may not even had hit at all).
The rear differential becomes a good idea when the car is fully lifted and the Primitive rear subframe kit is installed because the rear differential then becomes a relatively low point. That kit probably causes something like 1.25" drop.
On a car without the rear subframe kit, the rear differential is much higher than the lower points, which for you are now the front and mid plate at about 0.5" less clearance than your exhaust.
Don't know if this helps...
