The pipes rotted out and the muffler is no longer attached. I have a new stainless exhaust but I need to remove the old which of course is frozen solid. I can either go back all the way to the exhaust manifold or to the first connection away from the manifold. Anyone know of any tricks to getting the old pipes off. I've never had to do exhaust work.javascript:void(0);

Hi Tom,
Assuming you are in your own garage.

Wear goggles. Rust in an eye is a great way to loose that eye.

One thing I would not do is use a torch or open flame. The risk of a fire, no matter how slight, does not seem worth it.

To remove the bolts in clamps it is usually easier to tighten them until they snap off. They are probably rusted and will be hard to back off the nuts. Or cut them with a die grinder.

You can cut one or more slices in the outsie pipe at a joint. This will allow you to break loose the rust that holds them together and allows you to open the joint to get past the places where the clamp deformed the pipes.

Cutting the pipes into shorter sections may help. A rotary tool like a die grinder, either electric or air powered, with a metal cutting disk works for this. You can also get handles that fit over the end of a hack saw blade to make it easier to use in confined areas.

And wear goggles.

Let me think, is there anything else, oh yes, wear goggles.

Good luck

Thanks Tom. You had the same thoughts I had and the removal went off without a hitch. I had spoken with the shop owner that maintains my everyday cars and he suggested heat - and lots of it. That would have been a lot more work and as you note, a higher chance of fire. - - And I wore my safety glasses. They are indispensable when working under a car.
