The cast iron manifold I got had a crack in it so I (actually my wife) took
it to a muffler shop and had it welded. The guys there were skeptical about
the outcome and how long it might last but they did it anyway. The manifold
held up really well until my car came down with a bad case of "high RPM
backfire" and that eventually spelled doom for the welded-up manifold.
They did the welding for free which was a lot better than $300 for a new
cast iron manifold! (I now have SS 4-2-1 headers.)

Is this cast iron on your car?
If it is, report back on how the welder attacks the repair and
how well it works.
I've never had much luck welding cast iron because of the nature
of the material. When heated up it emits all kinds of sooty crud
that makes welding almost impossible.
I'm sure there is a way to do it, I'd love to know how.
