Stuck on removing severely corroded exhaust flange nuts that resist all manual and power tool attempts, leaving the user stranded with no vehicle.

Existing methods (heat, penetrating oil, nut splitter, sawzall) fail on heavily corroded, heat-cycled nuts that are essentially welded together; no tool specifically designed to remove such nuts quickly without damaging surrounding parts.
