This can happen from fatigue as they shouldn't have had to touch your exhuast manifold, though it is possible they did. Some shops perfer to remove the exhuast to do a catalytic converter, others will just lift the car and brerak loose with a cutting torch. It really all depends on the shop's policies and procedures. Have it check by another mechanic for a second opinion because really, both could happen.
