Logo exhausts; yet another brilliant way to make brand-conscious car owners part with their money. Audi;s interlocking rings are perfect for this application, while the BMW roundel may need to actually spin and sound like one of those whistle rings you had as a kid. Mercedes would have no problem with their three-pointed star, while Porsche may issues with their shield-shaped coat of arms.  Really though, When someone is douchy enough to do this, I think the best end piece for their car’s tailpipe is a good old fashioned potato.
