Its common place to turn a rounded off nut with a sharp chisel
I first point the chisel straight into the nut to get a bite and then angle
it in the so the nut turns counter clockwise.
This often results in the nut splitting and that's ok just use a vise grip
to spin it off
Bolts can be a little tougher I often drill or cut the head off and remove
the exhaust flange and this gives me a short stud to hammer on and grab with
my favorite stud removal tool channel lock 410 pliers

they are what vise grip wish they could be
Stud damage is a mater of percentage if the threads can be restored with a
thread chaser and hold a nut tight thats all it needs to do
