My 2001 Jeep Cherokee
 

I had recently bought a 2001 Jeep Cherokee. After looking at it for a while i noticed that i had 2 catalytic converters and 4 02 sensors. Can anyone help me out with this and why is that

New emission standards on all new vehicles.

can i take the two off and just make it one.

theres one on your header and it will most likely throw codes and wont pass emissions if you replace the headers. i replaced my stock cat with a stock replacement one and i haven't had any problems with emissions yet ::fingers crossed::

if you can, try and stay away from aftermarket cats. i have heard many storys that they either dont last long ( emission control wise) and that they throw codes left and right, but i have also heard they work well. im sayin if ya can get jeep cats to help ya out do it.
