my car doesn't have a CAT, and there is the occasional backfire. That means my car is running rich right? This may have no relation, but with my CAI, p&p head and header, it should be running lean right? so that does mean it's good? as in safety wise? I mean, does the increased air flow counter the lack of a CAT?
