The entire exhaust from the back of the heat exchangers will fit .... but
not legally as there is no cat. converter or gas recirculation.
I am running a stainless steel all in one piece exhaust from Bus Depot on
my 1982.  No crossover pipe needed, only the muffler
and tail pipe.

Just make sure that the flanges from the heat exchangers are the three
bolt trapazoidal ones.

Bus Depot part number:
071 251 053EK
