What size O2 extentions with QTP headers?
What size O2 extentions with QTP headers? What size O2 extentions is everyone using with their QTP headers? On QTP's website, it says you need 2, 24" extentions, but some people say they are too long. What works best?
A 12" on the passenger side and a 24" on the drivers side is usually sufficient. However, beings QTP headers are slightly longer than others, and they have it on their site, I would recommend the 24/24 extensions.

What is the advantage of using the 'vette rear O2 sensors? I have seen people recommend them but never an explanation of why they are different / better.
Thanks for any input.

One issue with stock O2 sensors plus extension may be that the
voltage drop along the longer wiring harness will be higher than stock,
so the heating of the O2 will take longer as less voltage drops on the heater inside the sensor (the heating occurs with the square of the voltage).
Thus a longer heating delay might trigger PO135 saying it takes to long to
heat the sensor on cold start. Perhaps the heating element for the corvette
reaches temperature faster with a lower voltage or the wiring is higher gauge
so as to drop less voltage along its lenght.
I have not checked any of this so its pure speculation.
