So I have been told that Emissions Testing has changed completely. Ive been told that they no longer hook up the pipes to the exhaust but that they just hook into your OBD port and if everything is Kosher then they send you on your way. Now im curious I dont have cats on my car and i would imagine that without those my car would not pass emissions. Now my question is if they only hook into your OBD port and there is no trouble code for the cats not being there am i in the clear?? I have never thrown a check engine light so i would imagine that it was taken care of with the tune or the programmer
