They can ping if the poppet valve isn't functioning properly, usually you'll generate a 402 code when that happens. I would check the EGR valve anyway - Suck test it.
Also they can ping if you loose a socket and it falls down by the knock sensor - that can screw up the timing /fooling the sensor. - If the socket sits on top of the heater core/waterpump hardline, that can also effect timing as that line runs close to the knock sensor..
To much compression from carbon build up is common as well.

This mod SHOULD work any OBDII compliant vehicle from 96-present if you are throwing any kind of insufficient catalyst code, as long as the sensors are still placed in the exhaust piping. It will work like a charm if you do not plan on running cats.

i think he wants to do this mod on the front o2's....that would be very bad the front o2 ajust A/F ratio. if you take them out of the exhuast stream your truck will run very bad and either run rich or lean not sure witch one but it wont help.
this mod is for the rear o2 senors only because if you have cats the rear o2 tells the computer the cats are workign...without cats it sends a code to the computer and says the cats not working and trys to fix it but with this mod because the o2 is only getting a lil amount of exhuast gases it tricks the o2's into thinking theres still cats...thus no codes.

hope thats what he ment other wise i went on a pointless rant lol

ok thanks just to clear things up i am not doing anything with the front 2 sensors just screwing them directly into the headers. just using 02 mod for the rear. with that done what people are telling me if i don't have enough back pressure i will be loosing torque...if that true then i am not going to run glasspacks, just some sorta of mufflers, any ideas or info.

I just installed the OBX headers. I installed the front O2s without any non-foulers. I used one non-fouler per O2 on the rears. 400+ miles and no light at all.
