help!!! how in the he%$ do i get the exhaust pipe clamp off my turbo

[bears4x4]

im in the proccess of removing my engine, the only thing holding be back at the moment is the dang clamp that holds the manifolds to turbo assembly wont come loose, prybar-nothing, we even hooked a 1500lb ratch strap to it and it poped off- i even grinded a hook on the end of the ratch strap and nothing, just poped off. i tried unbolting the tubing from the manifolds but 10years of heat has foided that plain, i cant even bust the bolts loose there either

when I replaced my pedestal O-rings, I had to get under it with an air chisel...

I got it off, a long pry bar and a rubber mallot, 1 hour later. It finally came off this was the hardest part in the whole engine removal, this took the longest. man that sucked
