Hey Everyone,

Does anyone know where I could find something in writing or whatever that these cars came with to cats? I have a 91 Z28 if that helps.

Cause the exhaust shop needs like proof that these cars came with 2 cats as well I seen it in a book that i'm able to change too 2 cats but that was at a different shop though. He tells me that he has never seen a 3rd gen with 2 cats I told him my buddy has a 92 25th Annerversary Z28 with 2 cats stock the way it came from factory and hes the 2 owner.

Thanks. Tony.

 

Do a search for RPO code G92... that is a performance package that includes dual cats.

 

Also, check for RPO code 'N10' on the decal that defines what the car was originally equipped with; I believe that was the designator for dual-cats on the '91 Z28.

My car is a 91Z came from the factor with dual cats has the G92 and N10 codes.

 

Hey Don,

But my car came stock with a single but I want to updated with 2 cat's for the reason that im gonna do a dual exhaust setup. Am I allowed to do this? legally?

Thanks. Tony.

 

Since it was an option on that model ....yes.

As long as you do it like this:

 

looks good, don. you buy that y-pipe make it or have it made?

 

Your talking to Don on this one, of course he made it himself, duhh. lol. Just kiding man. But it looks great though.

Tony.

 

Hey Don,

Thanks for the picture that helps out a lot.

Thanks. Tony.

 

i thought you where going with the true-dual exhaust????
.......ask in the socal section, and you might be directed to a 3rd gen friendly shop.

*edit* we have a sticky

 

Yeah I know im going with a true dual setup is just that the guy at the shop wanted to see how they put the cat's side by side since he's never seen a 3rd gen with dual cat's.

Tony.
