Catless headers are not allowed. Reason being is because under the visual inspection we need to input modified for the visual catalytic converter test. So its not about emissions its about the visual.
For readiness monitors.
2000-newer cars only EVAP monitor can be incomplete for car to pass.
1999-older only 1 monitor can be incomplete for car to pass. either monitor is fine.
Some counties dont require dyno test which are areas that have only basic testing and not advance testing. Major cities are advance testing which we use dynos. But since the Smog program changed in the summer its completely different.
How do I know this.
I am a smog tech that has a shop. thats all
