The part you linked is the defouler trick. I've heard of it not working, but the vast majority of cases it does.
Does CT do a visual of the underside? That's the only problem with moving it back.
Anyway, try the defouler trick (or simply buy the pre-made setup you linked) and see if it works. If you get a code you can try something else.
Make sure you put in on the second O2 sensor. The first will/should get the same reading as before the header install.
