i recently install a dc header, and the problem is that the sensor hole for the new header is at the top of the header. my old header sensor hole is at the bottom, the sensor cable isn't long enough to reach the top of the new header. what can i do to extend the sensor cable, to turn off my check engine light,

 

either 1) cut and extend the wires for the o2 sensor yourself using your own wire OR 2) get an o2 sensor extension from somewhere online

try http://www.rywire.com or maybe http://www.overnightautoparts.com has some

^^Thats your cheapest and fastest solution. Just make sure you solder the wires or use really good butt connectors.
