I bought a Walker exhaust (cat back) for my 94, v6, 4wd. It looks fine, except the middle pipe, forward of the muffler, that connects to the cat, seems shorter than what is there, and does not have a connection for what appears to be a second O2 sensor.

The engine compartment label says it is a non California model. None of the after market muffler people seem to carry a California model. And none of them show this extra connector.

There is another O2 sensor (I presume) ahead of the CAT. Would it be safe to remove just ignore the second O2 sensor and disconnect it?

Where can I look for more information?
