Hi Well I recently bought sport headers @ sport exhaust . I have put everything on . I have been reading and just don't know what to do with the o2 sensors ? Haven't started the engine yet . I really don't what codes popping up / or want to worry about screwing up the engine readings . I don't mind putting back on stock headers to get it to pass smog every so many years if so ? What the BEST or correct way to solve my issues ?
