Does every Jbody have a o2 sensor in the cat? im looking to buy the 94035 cat but i heard that some people dont have an o2 sensor in the cat. just want to be clarified on this because it was confusing me since i thought all the cars had 2 sensors, in the header and in the cat.
That cat should be good for your car, you're OBD-II if I'm not mistaken, and the 94035 has the o2 sensor in the cat for OBD-II ECU's.

Blown.
i beleive as long as your car is a 96+ it has 2.. the 95 2.2s might have 2 but i think 95 they were all OBD-I but i could be wrong..
thanks for the help guys.
