Default Remove weld from exhaust pipe

Previous owner replaced mufflers. One side has crappy “expand pipe to allow adjustment” then weld. I have no torch and my grinder can’t fit all the way around pipe. Been grinding and cutting around bottom. Any suggestions on how to cut and grind in top? Also best way to smooth weld bead?

numerous reasons not listed here why job being done at home, no choice

One of these can get in tight spots, Best Exhaust Pipe Cutters 2023: For a Clean Cut (autoquarterly.com)
If you have an Autozone nearby you could probably borrow one from them.

Do you have a Sawzall…, or even a jigsaw with a metal blade would do.

Bottom line - new pipes went on smooth as butter. the old pipe was marked to show how far new pipe should come down. Put exhaust clamp medium tight about 4" from end and tapped clamp with hammer to move it into place. Straightened pipes and tightened clamps. No leaks and sounds great.
