Stuck bolts between turbo and catalytic converter

Once you climb above 100 ft lbs, or shoulder muscle pull on a one foot bar, if you don’t clear thread friction you will break the bolt, either round the head off or snap it. Heat, lube, cold, or impact before you get to this point

Thank you all. At the end I went to a local shop since the access was very limited for me to heat with a torch (turbo is behind the engine). He was able to apply some heat, he added some lubrifiant and waited overnight. He was able to remove the screw in the morning.

How did you get on in the end I started my removal today I had a 4ft bar on them and they still wouldn’t move,
I will try the heat thing next.
