cat. removal question

it's getting more louder everyday. and i don't have the money for a new one at this point in time. if i remove it and add just a straight pipe, what will happen with the o2 sensor. will i be a getting a bad reading of some sort. thanks tim

What's getting louder? The cat is broken rattling inside? What caused the Cat to fail? What year is your jeep ? How many miles? The jeep will be louder without a cat. Be illegal in many states. And will cause a MIL lamp illumination on any OBDII system for Catalyst efficiency.

just buy a catco cat off ebay or a mailorder joint. they're like $40.
