The anti-fouler goes on the SECOND O2 sensor, on the midpipe, NEVER on the first air/fuel sensor on the header.
And, if you didn't before, disconnect the battery for 10 minutes to force ECU re-learn. You'll get more out of your new header if you do.

Thanks for the tip Garm! Would it work the same if I just unplugged the ECU itself so that my radio doesn't go all stupid and lose its settings, or do I need to disconnect the battery from everything?
pennyracer, I can already tell some improvement, most noticeably on the low end. The torque feels better and the acceleration is smoother. I also have a HK axle-back, NST 10% underdrive pulley, and AFE short ram intake. With the combination of the other 3 mods I had a weird slowness during accel until the car got to about 1500ish RPM, after which it would launch proper. Not sure why that was the case, but with this header it's a much smoother acceleration.

Also I see you mention getting it tuned in other threads. What exactly does this entail?

I would disconnect the battery. Best not to fool with your ECU.
Break a pin = dead car Tuning involved wiring in a management system and tuning on a dyno with someone who knows what they are doing.

Sounds expensive. Is it worth it?
