you just need to splice in a piece of wire for each wire there is to the desired length... maybe you can use the CEL fix to lengthen it;)

Aftermarket headers have been known to give you a cat inefficiency CEL, due to the fact that they do not hold heat in as well as the stock ones... To eliminate this, you can get a CEL fix that goes right before the 2nd O2 sensor that sends the correct reading to the ECU, therefore making the ECU think everything is running smooth and keeping the light from coming on...;)
