Default Rounded off exhaust manifold bolts - help

This isnt on my T/A, but im sure some of you have had the same problem.

Im trying to remove the Y-pipe from my 98 blazer, and while trying to unbolt the Y from the manifolds, two of the nuts rounded off.

Now if it would have broken off the stud i could have atleast gotten the Y-pipe out. I have no clue what to do from here, access is very limited.

Anyone got any good ideas?

Cut the nuts off, or soak with pb blaster, then hammer the next size smaller socket on the nut, and twist

also if your not near any fuel lines, i have used a torch and vise grips but if your space is limited i guess that wouldnt work.. i just had to hacksaw off a bolt on my 84 camaro's y pipe it was double nutted on the bottom , the bolt jiggled around but wouldnt come undone and i didnt have any help availible to hold the top wrench so i just hacksawed it off, took along time but if you got a fresh blade it shouldnt be bad, just go slow when you get close to the end so you dont cut your y pipe too.

a friend of mine as the easy bolt-out bits, that generally accept an 1/8" range of diameters, one might be 1/2-5/8", for example. They're like an external easy-out...when you twist left they dig into the bolt. I bet they'd be ideal for manifold bolts. Here's a Sears listing for clarification.

Bolt-outs and bolt removers are your friend. But, if all else fails, there's not much a sawzall can't cut through!
