Arrow Headers

[Butthead]

Considering picking up some, what happens to the o2 sensor, it it still used or is there a provision for it in the headers or does it become redundant??

If you run a PCV as well, you unplug it and remove it. If you aren't running a PCV, there is a hole ready to put it in. Simply unscrew the bold and screw in the sensor. Mine is still attached to my old headers sitting in a cupboard in the shed. I have the arrow headers on my bike, you will lose a little down low compared to stock, but gain up high.
