"I'm also curious about the labrinth of exhaust pipes under the SA bus which
seem to go forward from the engine and take a trip to about half the length
of the bus before taking a 180 degree curve to the back of the bus finally
exiting at the the rear. I wonder if that set up could be developed for the
Tiico conversions and if it is the extra length of exhuast pipe that would
cut down on some of the exhaust resonance, vibration, and noise associated
with the Tiico conversion."

Couldn't agree more. After living with mine for 8 months, I'd say that is
the primary element left to change to reduce the noise produced in the 3-4K
rpm range.
