'94 Geo Prizm, Rusted Exhaust Bolts/Nuts?

Q: I have a '94 Geo Prizm with a cracked exhaust manifold. I was able to remove all the bolts except the ones that hold the exhaust pipe to the manifold. I can't figure out how to remove them as the bolt does not seem to have threads and is a hexagon shape with a nut up tight against the manifold. Do I remove the nut or the bolt?.........Vince

A: That’s one of those things that makes our trade so interesting. A seemingly simple task can become difficult in the blink of an eye. Your Prizm should have studs with nuts holding the exhaust pipe to the manifold. If you’re replacing the manifold just snap the nuts off. After all, the replacement manifold, if new, should have new studs. If you have to save, then it would be best to get your hands on a real torch (not a plumbing torch). Some real heat will free those rusted nuts quite well.
