So I picked up a 1990 K3500 4x4 with a 7.4L 454 engine last week and am looking it over when I notice it doesn't have a catalytic convertor installed and I live in an Utah county with smog testing. I have an appointment a a local exhaust shop and need to now what I should do for the meantime to pass smog and get it registered.
I have not had it but a week or so and don't know where I will be taking it long term engine and exhaust wise. Just looking for suggestions. Sounds like o2 sensor was replaced about a year ago.
