I have my exhaust routed forward at first on my conversion.  It leaves the
engine bay on the driver's side goes forward past the frame member comes
into a large first muffler then turns back toward the passenger's side and
comes to a second muffler under the small cavity behind the wheel.  This
system is extremely quiet as buses go, I can be sitting at a stoplight and
if the radios on I can't tell the engines on except for some vibration in
the stick.   At Highway speeds I can comfortably listen to the radio
without having to turn it up, a first for any of my vehicles.  Wind noise
while cruising is the loudest thing.   This is with the 1.8L Cis-e injected
engine.  I don't see why the Tiico conversion couldn't be modified for such
a setup.  The big issue is the exhaust manifold.  Thiers looks custom, so I
assume you could modify it or go with something like an old Dasher manifold
that routed the exhaust towards the flywheel side of the engine.
