2015 Headers

The check engine light coming on after the installation of headers is disturbing to me and tells me that the great computer does not like the new catalytics on the new headers. I would not be afraid of any harm to the motor as long as the air fuel ration is close. But I hate dealing with a check engine light coming on.

I want to do this mod, but I do not want to fight a check engine light every two days. There has to be a fix for this somewhere.

Best of Luck
