So anyone else order race headers for there Si yet? Anyways I wanted to know if this particular part will disable the CEL when I install the headers on the car. This part is specifically made for the EP3's that used a race header so Im guessing it should work on the Si?? and where exactly do I install this?

you are still the first to buy the race header.

last post in that thread - both links should work. I honestly don't know about the rsx one you posted, but I'm sure it probalby would work. Basically they are to make the o2 sensor think there is a cat functioning. They must plug into the o2 sensor. The race header is removing the cat, so it won't be getting a reading - throws a cel on your dash.

some simulators aren't fast enough to fool the ECU.. The RSX was known for that. Running KPro solved the CEL.
