Having a serious brain fart and can't remember if there is any real differences. I need one so I can pass emissions and found someone selling from a 93. I have a 95 (though I think I have 1st gen exhaust bits, it's hard to remember any longer to be honest).
So help me out here - beyond the extra O2 bungs, is there any real difference between years of exhaust and specifically the cat?
The rear pre-cat is different between the 1G and 2G cars. Its turned more on the 2G cars for the larger t-case.
If you are talking about the main cat, they are all the same from cars made 6/1/1992 - 1999.
I bet asa says that the part # is the same, but I wonder if the used ones are the same. OBDII cats are usually different.Quote:

If you have a 95, you dont need the OBDII, plus the OBD1 should be significally cheaper. 96+ requires the OBDII.
