Different cars have different cat converter requirements. My 1987 RX7 doesn't legally need to have a cat converter, but I need to meet the requirements for air care to pass, ie.because I don't legally need one, it doesn't change my measurements I need to hit.
I put one on to make it easier.
I still fail.
