Could someone give me a sense of what life is like in the Phoenix area without cats? What are emissions requirements? How do people/cops treat louder cars? (I'm not asking about FFE generally speaking but about local laws.)
Obd2 test only on newer cars. If your sensors are all on and no check engine light your good to go. Never been pulled over in my mustang and I do triple digits every day but I did add some extra mufflers because my setup was louder than I like. It's still loud though. If you drive a loud honda you'll get harassed a lot lol. And if you only drive 80mph you better not be in the left lane or you'll get run over.
