Exhaust to turbo bolts stuck

[blackrosenova400]

If you can get a hold of one an oxy acetylene torch would be your best bet. Never heat up the bolt your removing. Heat up its surrounding area and fast, as the faster you heat up the surrounding area the bigger the temperature variation you will have with the surrounding area and the bolt. Heating up the surrounding area will cause it to expand and thus free the bolt if there is enough temperature variance. An oxy acetylene torch is about the only thing that will heat fast enough to do this.
