Resetting the CEL won't work. There is a required number of cycles the car must go through first. Emissions can tell that the car was just reset.

dont waste your time with aftermarket cats - they just simply do not work.
unfortunatelly, you'll have to save up & get the OEM cat from the dealer. I know it sucks & that it is super expensive, but there is no way around it - speaking from experience...

I have an aftermarket cat (see gallery) & easily passed everything except... the Bastard smog tech actually crawled under the car, read the numbers on the cat and failed the car since the cat is apparently for a Chrysler. This is a new rule in California apparently - approved cats only.

Lesson #1 - Do Not take your car to a smog dealer that doesn't have a Free Retest policy.

A few days later I took it to another dealer & it passed. But this bull**** is getting worse and worse every year. The cat was legal when it was put on, now it's not. I wonder how many people are paying $1200 due to this stupid rule change.
