I think it would be unlikely that Audi would ever go to a dual exhaust system, 
for a quite different and more prosaic reason.  At present, Audis driven on the 
majority of the world's roads have their exhaust outlet on the side of the car 
nearest the centre of the road.  In theory, this helps to keep the fumes away 
from pedestrians.  A dual exhaust would not do this.

There's an interesting cultural difference between the UK and Germany.  If 
there is a single line of parking spaces along a road but at right angles to 
it, Germans will park facing inwards (so their exhaust doesn't soil the wall) 
and then reverse out.  The British will usually reverse in because it's illegal 
to back out onto a main road in the UK.
