Stripped bolt head?

I stripped the last bolt on the turbo that holds the downpipe on. I was using a socket wrench with the 12 point socket, but the last one(only according to the order that I took them off in) was covered too much by the downpipe to use the socket wrench. I therefore used the 12 point end of the 5/16"(I think, correct me please) wrench. It stripped. I had also previously applied liquid wrench to it, but it was of no use. I am replacing the downpipe with the ATS kit, but I dont want to hack it off. Any ideas?

If push comes to shove, then I will probably grind the head off carefully, slide the downpipe off, weld a bar to the remainder of the bolt to use as a fixed wrench, or use a cutting wheel to cut a line in the top for a flat head.

sometimes you can get an 8 pt socket and drive it on the bolt head and then get lucky and remove it. I know its tight fit in there, but give that a try, then you can replace the bolt.

Sockets wont fit in the gap with a socket wrench on it. So I would have to hammer it on, then put the socket on it. That wont fit either, but Ill go try it

The socket didnt even come close to fitting, but good idea. I just decided to grind it off. Got out the cutting wheel, didnt fit. Got out the dremel, barely fit. The available space is different than it sounds, and I cant really explain it.

But thatnks for you help...

So did the grinding work?
My chisel method involves aiming it at the side of the bolt head on the angle that will tend to turn the bolt loose. Then hit it with the hammer. It's an old method I picked up from my dad when we couldn't get phillips head screws out of motorcycle cases. It usually ruins the bolt, but bolts are cheap!

Yeah grinding worked, now the bolt surface on the downpipe is nice and shiney (about.5"x.5" of an area) and the bolt is trashed. I had to grind to flat surfaces opposite of each other and then use a vice grip to get it off.

I have also used the chisel or punch method, and if you have a pointed chisel for your air chisel, it helps in areas where you can't swing a hammer. I have also ground off bolt heads or hex nuts many times.
