For Laguna Seca, built and first raced in 1957, I have seen 
crazy/interesting/hilarious plumbing in order to point the exhaust away from 
the db reading zones.  Like turning the exhaust up and along the rear bumper, 
then along the driver's side (left side) of the car, then adding a Supertrapp 
on the tail pipe.  This is for track days during the week when the limit is, if 
I remember correctly, 92db.  The track is surrounded by relatively new and 
currently being built, as fast as possible, multi-million dollar homes.  
Coexistence in action.  Beautiful!  Peace out.
