Default Cat and O2 sensor

For a EX cat, is the O2 sensor plug in front or behind the cat?

Which one, there's 2. The first is right before the cat and the second is in the middle of the cat.

Oh, never knew that. Cuz I'm planning on changing my LX exhaust system to an EX's, and need to modify the oxygen sensors. I found these (http://www.car-stuff.com/performance...=555&category=) , and someone told me that the LX oxygen sensor is compatible with the EX. So I need 2 sensors then, one for before the cat, and another after the cat?

I don't know the exact lengths but the first o2 sensor is just long enough to reach if you're doing the lx to ex conversion. You'll need to extend the second sensor about 18-20 inches. I got a 12 inch extension and it was too short.
