So I got my first Gen Expedition with the 5.4 V8 in it, and the other day one of the Catylitic converters went out on me clogging the secondary Cat. That had caused a overpressuring in the exhaust and caused the piping in between to bust open clean. I have cutted out the Catylitic and have ran just a piece of pipe. I am wanting to remove all of the cats and run Catyliticless. What are some cheap but effective ways to bypass the 02 sensor?
