CATS n O2 Sensors

[Hummertech]

There is no simple fuse to pull to disable the o2 sensors. I guess you could just unplug them and run your headers with no sensors, your engine will definately not be very efficient and may even run a little crappy since it can't monitor if the amount of fuel it's putting in is too much or too little. Of course you will have a constant check engine light on also.
How about paying a few extra bucks and getting headers that have holes for the o2 sensors. Or taking your headers, and have a machine shop make you some threaded holes for your o2 sensors. Then all of the enviornmental wackos will love you for your concern for the envioronment. NOT.
