2001 Chevy Impala Catalytic Converter EO #

I took my car for a smog, I just got the car last Feb '10 from Nissan & the place I took it to for smog stated that the catalytic converter was changed,it's after market & didn't have a EO# so it failed smog. Nissan stated that it doesn't need the EO#. Does it need it or not in the state of CA?
Answer:

If it's in fact your Chevy Impala is equipped with an aftermarket CAT, it needs to have an EO (Executive Order) number. The smog technician is right. Return to Nissan, show them the failed smog check report, and demand a new California approved CAT or proof in writing from the current Catalytic Converter's manufacturer that the CAT is California legal and does have an EO number (have them supply the EO number as well obviously). Once you have this documentation you can return to the smog test center and present it to the smog check technician. He/She will then re-inspect your Chevy with passing results. posted by SmogTips Support
