Do Headers Pass SMOG?

i wasing going to get some DC hearders but i was wondering if i had to take them off everytime i got get a smog check even though its not all that often thanks

hell no DC is definitely CARB approved…whatever header (singular cause you only need one for a 4-cyl. car) you choose just check on CARB approval…usually the people selling 'em will be able to tell you if they are or not. but the major brands…Neuspeed, DC, Mugen, JUN, Toda…all have or are pending CARB approval, and come with a nifty little sticker you can put in your engine bay to show it.
