I have the engine out of my Eagle, and after experiencing how incredibly difficult it is to disconnect the exhaust from the stock manifold, I decided to replace it. I am going to purchase the Clifford header. I don't think the header will have any kind of holes for the EGR tube or the oxygen sensor. Since I have already done the motorcraft conversion and the ECM Test bypass, and I removed and blocked off the EGR, do I still need the oxygen sensor and EGR tube, or can I just plug the intake and not worry about reconnecting the oxygen sensor?
Thanks
