Another thing, my girlfriends dad (that lives in Kennewick) told me a few years ago that they were pushing for emissions testing statewide by 2010. I never heard about that before then and haven't heard anything since either. It would be worth looking into on your part so you aren't redoing them in a few years.

I agree with the cats, they will only gain you a couple HP, not enough to notice during day to day driving.
Not only are the pushing for state wide testing they are pushing for using California EPA guidelines,
