If the o2 sensor is still in the pipes , it is ok
if not have the adaptor fitted to the pipes and it will be ok
the sensor reports the gas composition to the ECM to adjust the air/fuel mixture
if the new pipes are pollution control compliant the adaptor should be already there
if they are not then you are achieving nothing with the different pipes but are actually decreasing fuel economy
