Is it possible to have Xerd headers and still pass inspection? For the past four years, the check engine has come on after installing the headers. Come to find out the O2 sensonsors were blown. I replaced them to get the sticker, only to have the check engine light go back on for the same reason a week later...prolly due to the headers, correct? Is there anyway to adjust the computer or something to keep the light off and still run the headers and pass inspection?
