You might try taking your dermal and cutting a slot in the head and use a screwdriver. Use an adjustable wrench on the shaft of the screwdrive to turn the screwdriver while pushing down on the top of the scredriver and keep it as stright as you can. This works sometimes worth a try before grinding the head off.

Yes, go with the Dremel idea.
After you grind the slot in the head, apply some heat, (even a $12 Mapp or Propane torch will work if it's all you got)
One you break out the drills and extractors, the potential for making the situation worse goes up dramatically, particularly for first timers.

I would try the dremel & cut a slot in the head or use an easy out bit. With the countersunk head if you drill the head off there will be nothing left to grab it with.

Take a propane torch use a small tight flame and heat the bolt head a bit , you don't want it changing color just hot then whack it with a hand impact driver with big bit .
Had a few I've had to take the dremel and cut a slot in the head and use the flat blade driver , otherwise grind the head off and pull the cove and use vise grips on the stub .
That's all the dirty tricks for frozen screws on imports I know , good luck bud

Kroil is NOT a permanent lubricant. try it and find out...
get a piece of flat metal, spray it, in a different spot spray wd40, in a different spot put a drop of used engine oil...one week later slide your finger over a dry spot and then slide your finger over the other spots.
I didn't beleive it either until a machinist had me do this test...

One thing you might want to think about if you dont mind messing up the flange. Is there room there to drill a series of small holes in the flange to possible get the portion that surrounds the screw to break away and then grab the screwhead with vice grips?

I would first drill the center of the bolt with a 3/32 pilot drill to a depth of just past the tapered head .Measure the od of one of the old screws and use a drill bit a little smaller like .020".Drill again just past the head and this should allow you to remove the exhaust and expose the screw.
Soak it again with some PB then you may be able to grab the screw with some ViseGrips.

The only problem is if the screw does not unscrew,the Sears tool will just cut the head off.

honda uses the same style screws to hold the brake rotors in place for assembly purposes. they get froze all the time. i use a pointed center punch and tap gently on the outside edge putting a small dimple in the screw head and gives me a starting point. now i reposition the punch on a angle to drive the screw CCW and give it a couple of good smacks with a hammer. i use a general 16oz shot peen hammer, nothing bigger or too small. 98 times out of a hundred it will pop loose.
good luck.
