I just tried today to smog check my car but won't pass on the 15mph test under NO (PPM) section

Max MEAS767 1568

those are the two it failed, the guy said it might be my EGR valve or cats, since the previous owner put some cheap universal cats,,what do you guys think it is,,if its the cats anyone recommend any good cats
