Going ti install my O/R x pipe this weekend. Are they needed on a 94? See they are listed for 96 and up?

Not needed. Contrary to what the auto parts store clerk says, there are only 2 O2 sensors as Memphis stated.

Correct - you do not need MIL eliminators on the 94-95's. Swapping the cats out will not throw a CEL.

the 96 up cars need them because they have 2 sensors on each bank. the first (before cats) checks on how close the a/f ratio is to stoich then sends that to the computer for fuel compensation. the second (after cats) just makes sure that the cats are doing their job.

since we do not have obdii we only have sensors before the cats. and no sensors to make sure the cars are working. thus no mil eliminators are needed
