The back side of my car to the left squeaks even when i'm not breaking so it cant be the breaks. What could it be from? And when I got my exhaust pipe underneath fixed it started squeaking! Also, when I turn my wheel to the left it squeaks and when I go inreverse.
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.
