Re: how to free a stubborn slip joint? (lam)
Cut around it. If the part you want to keep "owns" the slip part of the joint, use a cold chisel to open the joint a bit and rotate the part you wish to remove bac and forth. Bang on it with a healthy hammer. I have generally found (this is experience here) that if one part of the exhaust is going its time to replace it all. I would get all the parts together and replace it all by cutting it into convenient pieces. Its not that much more expensive and if you are under to do one you may as well do them all.
