My vehicle is California emissions and after hours of research . I saw that I had to buy a California exhaust system to fit my car which I have from rockauto. Now I see that the cat converter has no port hole for my already there air sensor plug to install into. My old cat converter had a port hole just past the cat.heading towards the muffler. I can't understand what's going on. ? Either I have the wrong cat or my exhaust system was modified ?? I don't know and can't tell? Thank you kindly tony
