1973 Pontiac w/ 4bbl 455 V-8. Broken stud on passenger side exhaust manifold where the exhaust pipe bolts up to the manifold. The other stud is intact. The exhaust pipe is the male half of the fitting (i.e., it slides up inside the short pipe on the manifold). How do I get the broken stud out, and are there any workarounds that would let me solidly attach the pipe to the manifold without getting the stud out?

You may be able to drill out the flange and just use a bolt with a nut on it in place of the stud. Or you can just get rid of those crappy exhaust manifolds and get some headers

Is the hole for the stud blind or through drilled?

Appears to be drilled through.

A stub, but not enough to pass through the exhaust pipe (moveable) flange and thread a nut on.

Apply plenty of penetrating oil on existing fasteners,let soak.

Secure 1 12pack of prefered libation, 2 replacement stud/nut assemblies as well as replacement donut gasket and hi-temp anti-seize lubricant.

Remove remaining nut , move exhaust pipe out of the way. Use vise-grips or stud setter to remove both the broken and unbroken studs, replace with new studs, apply anti seize liberally to all threads involved.

Insert new donut gasket and re-install exhaust , start engine test for leaks.

Apply libation liberally.

OR.......buy a small pair of vise-grips and install clamping the 2 exhaust flanges together on the side with the broken stud.

This will fix anything exhaust related.....It'll help you get that "Performance Tone" out of your big block too.
