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.
