How many O2 Sensors

I have a 95 XJ sport and have only found one 02 sensor just past the manifold. Should I have two, with the second sensor past the cat or muffler? I had Midas put on a new Muffler and Cat that I bought online, but I haven't seen any sign of cut wires where they might have removed the second sensor if I had one. Thanks!

Nope, the post-cat o2 sensor on the 48-state emissions package came in for '96 (when the computer changed)

In 1996 chrysler switched to the OBD II system that blessed us with not one, but two sensors, that was my attempt at sarcasm. Don't go looking for more and be thankful you can run a hi-flow converter.
