O2 sensors & cat removal

2000 Ram 1500 5.9, Auto, Headers, K&N Filter System, Computer Chip mod
I have headers that come into one cat then split out into dual flowmasters
What needs to be done to the front or rear O2 sensor if the cat were removed?

What do you really think that you are going to gain by removing the cat?

Actually, that would be your descendants, not ancestors.......not that I'm splitting hairs........but I agree with you. JasperP

.. and, there's nothing in unprocessed engine exhaust that'll be any harm to the ozone layer.

Suddenly, without warning, dingy101 exclaimed (20-Nov-06 10:16 AM):

How did you get a feline stuck in your O2 sensor???

If you remove the cats it would be illegal to drive it on a public Highway. IF stopped you face the prospect of a VERY BIG fine. Headers will hurt your performance on a street vehicle The only gain will be in the upper RPM range & it will COOK everthing in the engine compartment from the extra heat. Not worth the agravation IF you must?? use a cat back system

I would't remove the Cat if i was you, use a cat back exhaust system if your looking for a better sound. Also removing the Cat could cause engine problems if you have a downstream O2 Sensor.

Gary, Since no one else has given you serious info, I will. I have nothing against hot rodding, if done correctly. We do live in a different time now and the wife's tale once told that you cannot make serious HP with a CAT is simply not in touch. There is a rub, when you are done, the vehicle must pass the 4 gas analyser test. So, you don't remove the O sensors, they are necessary for the computer to work. Headers and dual exhaust with dual converters work fine. Be very careful with cams. Long duration cams will not pass. High lift, fast ramp cams will pass. Watch your valve centers. Cams with valve centers lower than 108 degrees won't pass. Crank driven superchargers will pass. High compression pistons do not pass and you can't get good fuel 9.5 is street max and you may not pass the NO test. 9.0 and you will. If you use dual converters, don't use big ones, they won't get hot enough to function. Good luck, Steve

Summit Racing sells a plug in module that will "simulate" the output of a functioning post-converter O2 sensor. It's not street legal, of course. Leave the pre-converter sensor on one bank. Then he can have his long tube headers and straight dual exhausts.
I sure hope he doesn't live in my neighborhood.
