For what its worth, our Caterhams with full mufflers are at about
83 or 84 db (and you can hardly hear them on track). Around
here most tracks require 103 db, and we can easily meet that
with a bullet-type muffler and pointing the exhaust away from
the sound meter.
81 db is definitely very quiet - very close to what a street car
would be, I'd guess.
