I had a nut that connected the muffler to the exhaust port. Rusted and I tried everything I had. PB Blaster, had impact wrench, etc. Didn’t have a torch. The biggest problem was a socket would fit because of the muffler flange, and an open end would round the nut. No turning radius for a vise grip plier.
My solution, for those having a similar problem, was to drill a small dimple, about 1/8”, into the nut outer perimeter, not the face, without going very deep. Then with a nail punch and small hammer strike the nut, in an angle to cause it to turn ccw. Drill another dimple as needed, etc. Keep working around the perimeter as needed.
This won’t work for every problem, but it worked for me. Hope it will help others. (Also doesn’t ruin the nut, other than a few dimples.) |

John Muir has a similar method involving a cold chisel. It works. _________________ "I haven't seen one of those since I was shootin' at 'em!" |

Next time, you might try a 13mm obstruction wrench and a little Kroil. |

The obstruction wrench would not work. The problem was there was not enough room to fit a socket or closed end wrench, because the nut was too close to the flange weld. Have no clue how it was tightened, but the open end would fit, but would round the nut when I tried to loosen it. |

Sometimes you have to grind down the wrench a little so it fits, but they do work. Was it a stock exhaust or a header? |

When it was tightened it probably wasn't rusted solid and an open end wrench worked. _________________ “If you care for a thing long enough, it takes on a life of its own, doesn't it? Mending old things, preserving them, looking after them – on some level there's no rational grounds for it.”

My thought exactly. |

There are wrenches that won't. The snappy "flank drive plus" is what I'm familiar with but there may be cheaper versions out. Yes they'll mark your fasteners up, which is something to keep in mind, but they're notched to grip the fastener away from the edges. The open end will break the bolt before it rounds the nut. _________________ 65 Beetle
