My buddy has a 2007 F-150 5.4L that I sold him. It needs an EGR Valve (which was known) and Catalytic converters replaced according to Ford's mechanics. Apparently the exhaust had a pretty big crimp in it and was restricting flow majorly, ruining the cats. Anywho, he wants to get rid of the catalytic converters and bypass the 02 sensors. Is this even possible on an 07, not worried about emissions either.
