Default Check Engine Light - Header Install
Installed Dynatech Supermaxx headers about 3 weeks ago. Wow! Three weeks later my check engine light came on. The dealer claims it is due to the headers. Evidently 2004 Z06's electronics are very sensitive to headers. Per dealer the light will eventually come back on after the codes are cleared. They claim no harm is being done.

Any other 2004 Z06 owners with this issue? Is there a cure short of LS1 edit?

Thanks for the advice.

How far back did you put the 02 sensors? Too far back and they won't heat up enough and set a code for you.

Please list the codes. I had an AIR Injection System error code that came on. The dealer changed out the check valves and solved that issue!
