So I'm guessing you have already reset the code, and the light came back on? Probably bad cats. (That would be my guess, at least)
Are you sure the 02's sensors aren't bad?

i was thinking that too.. but one cat is off a 2002 30k mile ss and the other is for a 98 ws6.. but its werid cuz both said they are bad.. and i doubt that happens both being bad like that.. and no other code came up for 02 sensors unless codes dont come up for them?

Yeah, you are probably getting P0420 for the cats, and the car will throw a code for a bad 02 sensor.
