I've never heard anything either way about Bosal cats, but this is surprising that someone's jig would be that far out of alignment.
You might also check with the company to see if they will reimburse you for modifying it (and still warranty the unit); cut, turn to angle, reweld. That would be faster for you and cheaper for them than shipping both units back and forth, and it won't hurt the unit so long as you don't cut into the cat or the flex coupling.
Good luck.
