I've searched all over the web and can't find what i'm looking for.
I'm building my exhaust in the jeep and will be eliminating the cat. It will be just 2.25" pipe all the way from the header to the muffler. I don't mind drilling holes and welding in some bungs for the (2) O2 sensors but I need to find a way to "trick" the computer into thinking that there is a cat in there and its working right. does anyone know the resistance values that the down stream sensor needs to read to keep from throwing a code and having the check engine light on? I'm sure plenty of people have used these newer 4.0L's in buggys and didn't run a cat, but I can't seem to run any of them down to ask.
Thanks.
