Throwing o2 code Question, Spark Plug Non Fouler Options

[6G96GT]

Welp, been out for quite some time but I am back to ask a question (hopefully Bitter will read this). I have two 02 sensors in my afternmarket header in the same location, one about 2" above the other. Why? I have no clue and yes it sounds stupid and it may even appear that I don't know what I am talking about but please beleive me...the header's 4 to 1 pipe (the 1 pipe part) has both o2 sensors in it and there is no cat or pre cat or anything at all.

So...the non fouler spark plug kit, will it work to put it in bank 2 ? I am throwing a code and says o2 bank 1 or 2 and I replaced bank 1 a couple months ago with an OEM one.

Is the non spark plug fouler kit a direct screw in fixer? I have no 02 in my cat at all. I even considered re-wiring the second o2 to reach my cat and add a bung and wld it right into it.

Help please?

you've got a precat sensor and a post cat sensor. seeing as you have aftermarket headders, (without a catalytic converter) then your error is due to the fact that your car is wondering why the exhauset is just as dirty before and after the cat converter. it's trying to tell you that something is wrong with your cat. (duh because you ain't got one )
