I have a 1995 auto Z28 camaro is this a dual or single cat car? What specifies one or the other?

 

95 z28's have the single cat, unless it was a california car(i think!). they also have obd1 computer, which the 96 and above have the obd2 computer, you can tell by looking under the passenger side rocker panel, you should see the 1 cat right there

 

All 1995 california automatic equipped f bodies had dual cats and OBD2. Otherwise, it is OBD1 single cat.

 

Not true - ALL 1995s are OBDI regardless of the number of cats. However, they do have an OBDII style connctor.

 

I believe Red is right.

 

My car is an auto california car so it has dual cats and an obdII style connector but obdI system?

 

1. Look at your "build tag". "YF5" is the code for CA emissions.

2. Look at your exhaust system. A dual-cat car will have a small cylindrical cat bolted directly to the bottom of the drivers side exhaust manifold, and a second cat in the branch of the "Y" coming from the passenger side manifold, but its flat and located under the hump in the passenger footwell. Then the pipes "Y" together. If you have a single cat car, there will be no cat under the drivers side manifold, the pipes will "Y" together in front of the single cat, also mounted under the passenger footwell hump.

ALL 1995 F-Bodys have an OBD-I PCM, and a 16-pin OBD-II "style" ALDL connector.

 

So a borla dual cat catbakc will bolt on no problem? Thanks for all the help guys It answered a few questions I had for a while. Here is a picture what is being talked about (mine looks identical) in case anyone needs it.

It's always good to get under there and get acquainted first-hand anyway.

 

So true.... but then 75% of the questions that get posted here would disappear

 

HEY!!! I work on my car and do everything myself on it!! It was 33 degrees the NIGHT i asked. Gimme a break i dont feel like crawling under my car when its dark and freezing so i thought i would ask someone who could answer it off the top of their head real easy.

 

Some of us live in apartment complexes where they won't let you work on your car in the lot. Mine won't let me do anything that isn't under the hood only and short in time. I took a lot of heat when I changed my TB out. It also hurts I live next door to my property manager. Which is one reason I'm glad I found this board so I can have questions answered with out the threat of being evicted for violating lease terms. BTW most apartments in this area use a standard lease for that the state drew up for them to use.

 

Damn that sucks, i tore my whole motor apart in my apartment complex and put it back together when i hydrolocked it...they didn't care...course that's in South Ga
