yes, a LOT of them do... I've had to do SEVERAL custom tunes for people on here, as well as from other forums, for LT headers installs...
not all LT headers require them or have the O2 sensors too far away... most do, but not all...
and those that don't post about issues, most likely have had those codes tuned out already since they have been custom tuned for mods already...
shorties don't have the problem at all...

Im NOT a tuner or know a whole lot about it but...since we are talking about something so small as millivolts needed for proper o2 operation and reading wouldnt different length leads have SOMETHING to do with it? I mean,I know the conduction of electric is very fast but since we are talking millivolts and longer conductors I would think its a good arguement. IDK

it shouldn't, right?? cuz the O2's are already heated up, right??
aaahhhh, but it DOES...
so why is that, if the O2's are still heated up already??? heh...

ok.. so, then once the vehicle has been ran a while and is all warmed up... O2's are still heated up... clear the code... then start it up and run it for a while... see if that light/ slow response trouble code doesn't come back again...

You're a sponsor here, and a tuner too?
I strongly suggest you learn some electrical basics before posting anymore correct information... like how a foot of wire cannot affect a sensor signal, without introducing resistance to the circuit through some other means (corrosion, incorrect gauge, etc). The only way a length of wire could "slow response" like you suggest is if the wire was several hundred feet long.
The reason you see the DTC(s) return after clearing is because of the restart, when the PCM checks for O2 sensor response. When you shut off the engine, the sensors cool. They take time to warm up to operting temperature again, even if the engine was only off for a short time. If it was due to just the wier extension like you claim, the DTC would at least show pending status IMMEDIATELY after clearing KOER.
I also suggest you make a standalone circuit of some sort using that extension, and do a voltage drop test. Post your results

longer wire has more resistance... requires more "energy" to get from one end to the other... takes longer... requires more energy to get from one end to the other...
electrons have more distance to cover in a longer wire than a shorter one... and if the wire is thinner, there's more resistance too... also, as the temp of the wire increases, so does it's resistance yet again....
granted, it may not be the ONLY reason... but it plays a part... and I even said in a previous reply that it is also because the O2's are further away... good lord... I quit...
doesn't matter... doesn't change the fact that the answer to the OP is still that he needs to have his tune re-done in order to stop those codes from being triggered and the CEL coming on, which is what this thread was about to begin with...
I'm done...

Ummmm, I think you answered your own question - I did not have it tuned after the headers were installed.
Slow response is pretty common up here in the NE.Takes a long time for 02's to work on the cold days.Match that with the car not dialed(tuned) in then you can easilly throw those codes. A retune would of been cheaper than buying 02 sensors.

Would be a good test to put your longer harness o2 into a shorty header or stock manifold and see if you get the slow response codes... I doubt it'll change a thing....
