i think if you replaced the entire exhaust with a straight pipe or just didn't run an exhaust at all i dont think that would affect how your car ran to the extent you described.
if the rear 02 sensor got messed up during the install i dont think that wouldn't make your car run badly since the rear 02 is just an emissions check.. dont think they would be messing with the front 02 sensor..
have a look under there to make sure all the connectors are loose.. and maybe your DPFE went at the same time as the install?
