I gotta agree.  As a chemist, the only place of I know you're really going
to encounter sulfur in the form of hydrogen sulfide (H2S) is in the
exhaust, although it still shouldn't be very common, and it shouldn't hang
around.  There is sulfur in the air as sulfur trioxide (SO3), and as Dave
pointed out, there's bound to be some in the gas.  Regardless of the
source, it all gets "burned" and is likely to come out as anything on the
exhaust side of things.  Do you get much flow from the tailpipe?  Do you
have stock exhaust?  Maybe it's time to try out one of those
high-performance cats.  Btw, you can smell hydrogen sulfide down to a
couple of parts per million.  Good luck.
