Ok, if I put a Race Header on, say, FC or FS, and put the FC catalytic converter on, will my car pass emissions? Cause you DO have to have a Cat. on you car in order to pass, correct? Probably a really easy question to answer, so please go easy. LOL
Thanx,
Tom

I would assume each state sets different standards for their emissions. But here in Washington, I have to be emission tested ever other year starting the 5th year. And I have passed emissions with flying colors with just a test pipe.

test pipe? like a straight pipe, replacing the cat?

Some states only require that tailpipe emissions meet standard while others will visually inspect for any modifications. If you are a "sniffer only" state you will be ok. In MO they only do visual if you fail the sniffer.
