As you say, a turbo effectively (very) acts as a muffler and muffles the
exhaust adequately sometimes even for San Diego (although, sometimes not).
The rule does not say exhaust must be "quiet", if that was the rules-makers
intention they should have said so, or just eliminated the wording entirely
and leave it up to local rules. But such is not the case.
You could also say that the direction of the exhaust effectively "muffles"
the exhaust or any other debatable excuses but again, if the SEB intended it
to be left up to local rules and interpretation, there would be no need for
it to be mentioned in the rule book. It should be easy enough to address in
supplemental rules for the event. In the absence of supplemental rules
though, the car is ineligible and only an exception by the event chair
should allow the car to run. (assuming an SCCA sanctioned event)

Of course what "properly muffled" means is open to interpretation. My
Evo running with muffler-delete and cat-delete pipes is still much
quieter than a lot of non-turbo cars equipped with "token mufflers"
because the turbo effectively acts as a muffler. I've seen cars run
this way at Nationals where people can be notoriously picky about the
rules and it didn't seem to be an issue.
I say if it's quieter than gunfire, it's probably fine for the
Candlestick Point area. ;-)
