My rear bumper is vented. Meant to post a picture for you last evening.

The bumper I have is fiberglass and the vent does a great job getting the turbo/exhaust heat out of that area. You can feel and see the heat pouring out when at an idle. I am sure this is one reason my paint does not bubble during track events.
