So I am trying to do a muffler delete..

I got the safety clamps off that hold the muffler up by the back bumper. Now there is a clamp that holds the muffler into the back pipe.. Here comes the problem.

The clamp has major rust because I'm up north and snow kills our cars if we don't wash them every week.... Anybody know how to open the clamp without cutting the muffler pipe?

Spray some PB on it.

As he said, penetrating oil works wonders

If you were smart I would replace it instead of jimmy rigging it. you will regret it down the line when you muffler falls off. Don't be cheap.

If after using penetrating fluid and it doesn't work you could also try heating the nut with a small torch (if its not near your gas tank). I usually just cut them off and use a 12gauge wire to hang the pipe while i plumb it in before tacking it all together then finishing the welds once i know everything is where I want it. If its sound your after its sometimes easier to replace a resonator with a glasspack (18", 22", 26" etc),
But thats my preference.
Might help to know what kind of vehicle it is?

As a mechanic I would personally cut the clamp off and replace it. They aren't expensive at all and will make the job a lot easier. If you don't have anything to cut it off, try going a socket size smaller and hammering the socket on. Then try to ratchet or impact it off. No matter what tho you should replace the clamp.
