Finned RAJO exhaust manifold question

Post by Popemcman » Tue Sep 12, 2023 2:33 pm

I have a finned RAJO exhaust manifold that is incomplete. The exhaust pipe exits from the bottom of the manifold. The missing part holds the exhaust pipe somehow. Does anyone know what the missing part looks like? Thanks. First time on the forum haven't figured out how to attach photos. Mike

There is an extension piece that routs the exhaust down from the exhaust manifold and around the water connection casting. They are pretty rare.

You can attach a header flange on some proper diameter pipe and it will work fine until you find an original.

Actually, any competent muffler shop should be able to manufacture you a suitable header.

Any idea the purpose of the 2 bolts coming out of the top of the manifold are for?

Not stock. Maybe for a carb air heat pipe.
