Both side... you got two cats and 4 O2 sensors. Do not just replace the O2 sensor unless you got an OBD2 scanner to verify it is completely dead.
Alot of time when check engine code spit out O2 sensor... it is the MAF that is bad once you verify that the O2 sensor is still working via the diagnostic scanner.
