Your mechanic should have expected a broken bolt when removing the old Exhaust Manifold. It is a PITA to remove them once they break, but never had one get the better of me.
I guessing the person you spoke to Friday did not know the H3 has a Pup Cat built into the Exhaust Manifold, but they later figured it out and now they are the wiser keeping your warranty $$.
