I thought there must be a functional reason for the exhaust placement and this very well could be it. The other thing I noticed though is the "truck nuts" muffler seems to be hanging down into the air that is flowing out from under the car. If aerodynamics is the reason for the placement of the exhaust, you would think they would tuck the car's nuts away.
