Realistically speaking though, I'd say an overwhelming majority of
cars running in non-stock classes, and probably a significant portion
of cars running in Stock, don't meet the legal sound limit, 95 dB(A)
as measured by SAE standard J1169 (distance 18 inches at a 45 degree
angle from the tip I think?).
What does 18" at a 45 degree angle from the tip have to do with a number
measured on a moving car at 100 feet?
