If you're referring to a std Corvair cast iron exhaust manifold, then I
wouldn't waste time painting it.
I'm looking at using a product called Calyx manifold dressing.
It's graphite based and you rub it onto the cast iron manifold. It protects
the manifold from rusting and gives it a natural look.

I'll relate my experience with exhaust stacks on my Cont A65 and A75. The stacks
on my A65 were standard Aeronca Champ type mild steel stacks with the aluminized
heat muff. They began to show rust spots and pinholes so I sandblasted
them and painted them with flat white rattle can VHT exhaust system paint. I
had access to a controlled temperature industrial oven so I was able to cure them
at the specified temperature for the specified duration. I ran them for another
year or two and again started to see rust through the paint so I pulled
them and had a talented fabricator use them as the patterns for a stainless steel
set. This fellow fabricated custom stainless exhausts for all sorts of engines
that were run in engine test cells, everything from big diesels to single-cylinder
snowmobile and motorcycle engines. Before I could run the new stacks
I swapped out my engine for an A75 and put the new SS stacks on it instead.
I had already purchased some Turbo-X from Techline Coatings to spiff them up,
but I never bothered... the Turbo-X is still on my shelf and my stacks still
look like they did after I got them and ran them up to temperature on a couple
of flights. I kind of like the color they've taken on and they sure don't
show any sign of corroding.
