thread knackered on manifold to decat bolt

[danh90]

was removing my decat today as its been blowing,and one of the bolts from the manifold to the decat the thread has knackered i think.

when im undoing it the nut its just spinning and no the whole thing isnt spinning just the nut it wont tighten or loosen at all.

ive had it back to the garage that fitted the decat twice due to blowing so dont know if they have over tightend it or something.

any ideas at all other than to grind it off

cut it off, get a new fitting kit
