Talking FSWERKS race header for my D23 PZEV? (Questions/tune)

I've read the basic bolt on's thread, but it didn't help much with my questions.

I want to put the race header from FSWERKS onto my 2.3l, I know I need a new flex pipe and cat, along with a o2 sensor cheat for CT emissions.

My questions are, why do I need the o2 sensor cheat and why does the header only have one bung hole on it, When there are three o2 sensors for this PZEV model?

Also, is this header going to fail visual inspections? If so is there a trick to it? Maybe a heat shield? Or do I need to wrap it anyways for heat?

And what is involved in the tune? I have the OE Exedy fly/clt kit, with the Weapon R intake, and the exhaust done in 2.5 diameter trubenz piping from the cat under the car, back.

Thanks, Hopefully Tom can stop by for the Tune questions, since I would probably buy it from him.
