Brakes can cause squeaks even when they're not being used, but the clue is the noise started with the exhaust work. Return to the shop that did the work and let them inspect it to see if the pipe or a hanger are rubbing on something. Some exhaust hangers have metal springs that can squeak, as though the designers didn't think of that. Repositioning them can help.
