97 db....that's probably what our car would do *with* mufflers...;-)
At Portland, they normally have sound limits, I think the top
limit is 103(?) Since they invited the Trans Am cars up, they
had to get a variance from the state, since none of the cars (well,
one did) have any sort of muffler. They gave us a 115 dB limit, and
a couple of cars still got black flagged. When the pack went past the
sound meter, it supposedly hit 120 db......that's *loud*...
