Show of hands please
 

Could you all please let me know how many of you had problems with emissions after installing a header? From what I hear the air pump has to be removed and I need to know how much this affects the emissions test. Also, do you really have to remove the pump and acv valve or can you just leave them there so the car will pass a visual check? Thanks!
