Charles, "properly muffled" is dependent on the site. Many sites do
not have sound restrictions, and an exhaust system without a muffler
can be proper. Rob's GT2 has a open exhaust muffled only by the big turbo,
and he has run at Candlestick. It comes down to just how loud the car
is, and where you're trying to run it.
Dennis, have you done any sound level measurements on the car? The
region's sound policy stated in the supplemental rules is 95dBA
measured at 100 feet from the car.
