I'm no expert on the newfangled (read: November 1964 and newer) type 3
stock exhaust system, but I'm pretty sure that pipe is supposed to go
from the fan shroud elbow forward to a hose that is connected to the air
boxes at the entrance to the cabin.  They've got flaps and are
themostatically controlled by (again, I believe -- not certain here) the
air that passes through that pipe/hose.  A protection added against
melting the inside of your car when they improved the overall heating
capacity of the type 3 by adding those small "upper" heat exchangers.
