my old 1997 had 02 sesnor problems ford told me it's ok they don't do anything
with and dual exhaust set up it is normal because it is not getting a even flow of exhuast or somthin like that, when i bought my 7700 it had true duals and that was normal fo the light to be on.

theres so many things wrong with this post I dont know where to start...
First off are they worth spending 50 bucks each on?? What kinda cheap sensors cost 50 bucks each?? Remember people you get what you pay for..
Secondly "they dont do anything and its normal for the light to be on"
oh man thats quite incorrect.. They keep your cat efficient and alive for one.. As well they allow your computer to achieve optimum air/fuel efficiency for Fuel economy, emissions and engine health. dual exhaust or not its not normal to always have a check engine light on (im assuming thats the light you speak of).

It is possible for the rears to be disconnected and the cel will still come on, but performance will not be affected. Tuning can delete the rears so no cel.

Correct. Rear 02s do NOTHING for the A/F ratio of the engine. Only job a rear O2 has is to make sure the cats are working...if they are not...the rear O2 will read it, and let you know by throwing a CEL. All your MPG, A/F ratio and calculation read off the front O2s...
