Thank you for the information! Were you able to feel the difference with those headers on your car?I was in your position just a moth ago. It's going to be hard to find a set of carb legal headers that are properly marked online.
However, my solution was to get the DC Sports ceramic-coated headers for mine. This is the one for your car (i checked). I got mine through Amazon for the same price, they came neatly wrapped, with documentation, CARB sticker, the works.

I figured that since I live in California, it would cause less problems for me when I need a smog check because the state requires for smog centers to check that all engine parts are CARB legal in order for DMV registration to become valid.dumb question: but why dose it matter what header you run, as long as your emissions system is working correctly?
