Souds like somebody didnt delete all of 10 codes 5 for each side " If I remember correctly" for the rear O2's.

Anyways using rear O2 sensors even if you have a Y-pipe with cats the car is still going to throw DTC's because the readings and operating ranges for the rear O2's can't be used anymore because your cats are farther back in the exhaust stream so your sensors will not be reading the values that they have been preset to read..
