but how can your car pass the inspection with no cat? I mean the guy at the inspection wont just go "Hmmm that looks like a catalytic converter right there, no need to test the fumes from the exhaust! I really wonder what makes that car sound so loud!" lolol
Not to mention the different odor of fuel a car without a cat has.
Not that I passed any inspection, but I would logically think that its not only a visual inspection, that would be useles...
