HHR SS How many cats?

Does the HHR SS have 2 cats stock? I bought mine with a Hahn downpipe and I only have 1 cat. Curious because of smog testing etc.

I thought in California the cat has to have CARB cert label on it if it is not from the factory.

Be sure to check for yourself.

Hey guys,
Thanks for the info. My smog place doesn't usually check for carb certifications. He knows me and usually just tests my cars and if they pass all is good.
