Wrangler Oman - I believe you are referring to the catalytic converters. Removing them and/or the oxygen sensors will most liikely produce an "engine" light and cause the engine to run a little different. I would assume it would cause the computer to run in a default mode and may lean out the gas mixture. Perhaps someone here can add more detail to that issue. You may have to have your computer recalibrated/reconfigured for the change. Removing any large restriction (such as catalytic converters) will result in more HP. However, you need to maintian some restriction so a muffler is required.

Do you have emission laws in your country? If you do and you remove the converters you may fail the test. If you do not have such laws, then I don't think this will be a big deal.

If you remove your cats and the o2 sensors your light is gonna trip and like MOz said lean out your Jeep. Mine ran like crap with 2 o2 sensors down. Ive heard of a kit to attach to your computer thatll make it think that your cats and o2s are functioning flawlessly, even if they arent even there. I think its called the o2 eliminator or somthing like that, look it up online. I plan to do the same thing when I get back, sounds real nice. I do have a question weather there will be enough back pressure though.

Wikipedia is the bomb ^_^ Underlined it for you.

What country do you live in btw?

If I were you, I would check into the kit CT-TJ mentioned befroe you eliminate the Oxygen sensors and catalytic converters. I think as long as you keep a low restriction muffler installed (instead of no muffler) I think you should be OK for the engine.

Good luck and let us know how this works out for you.

The front o2 sensor is the one the computer uses to monitor and adjust fueling. I would leave that one intact, otherwise, the engine will only run in an open loop mode causing a possible loss of performance and poor fuel economy. Running an o2 simulator on the front sensor will only cause problems.

The rear o2 sensor is only used for monitoring the efficiency of the catalytic converter. If the cat is removed, the light will come on. This rear o2 sensor connector is where you will either need an o2 simulator to fool the computer into thinking the converter is there, or you may be able to have the computer reprogrammed to disregard the rear sensor and any catalytic converter related codes.

Jus depends on which model you have. If you have the o2 sensor near the cat in the rear it will trip your check engine light. If you have the 4 pre cats, and all 4 o2 sensors are near the engine bay, then it affects nothing and increases horsepower and flow. Youll get flamed by the tree huggers but i have selective hearing anyhow

No wonder we're living in an environment threatened by global warming. Cars with Cat converter produce enough pollution. Cars with out it produce a lot more!!! IT IS THERE FOR A REASON.

x2 we have emissions here so we need it but if you want more flow get a hight flow one.
