One small question though. I assume theres no reason not to go ahead and put the sim in now even though my headers haven't come in yet? I figured it would be a good way to verify the functionality of the sim itself without the possibility of having accidentally switched any 02 sensor positions during header install. Plus it will be one less thing to do when the headers do arrive.  |

Hey guys I'll be emailing both of you to make sure you get this, do NOT do this, it is not how they are designed and will actually cause sizable issues.
If anything I suggest not installing them, even after you have installed the headers, until you throw a CEL, that way you know the o2 sensors were installed correctly. IE the CEL should be for cat inefficiency not swapped sensors.
