HELP ME PLEASE Header swap on 04 3.0 eclipse

six views and still no help great

I have good metal fab skills its just the safc2 or tactrix sensor I was curious about witch one is easier to use/install?

sorry just have had a hard time with serious help I need to know if the safc2 from apexi was easier to use and install then the tactrix setup or if I even needed them at all

I figured the safc2 and tactrix has something to do with the car if I put after market headers on wont it run rich and crappy?

I gues my point is are the safc2 or tactrix needed if I put on the headers are they neccisery

sorry for spelling was in a rush out the door
