Well, I asked a Porsche mechanic, we all know they're better than
Mercedes mechanics.  He explained that it all depends on what kind of
muffler bearings are used in your car.  Since Audi uses the new style
centrifugal muffler bearings,  which naturally draw air through the
keebler pin assembly, it's a moot point.
