I’m in Southern Cali...this might be dumb question but how will adding an CAI and/or exhaust effect my SMOG tests...in Cali we have to have these done every couple of years.

Will I have to reinstall stock set-up every time before my tests?

 

You should not have any trouble. A cat back doesnt effect your smog, most cai are smog legal.

well not all of Cali. up here where I live (mendocino co.) you only have to smog when buying a vehicle. yet another benifit of the "country" lifestyle....

but yea most "cat back" systems and CAI's are legal....

 

it'll say it on the box. my brute force said right on it 50 state legal.
