Will this fit a 96 z28?

They will "fit", with respect to bolting to the heads and fitting in the engine bay. The AIR connections will probably not match the diameter of yours. The EGR will be OK. You will have eliminated the dual cats, and need to decide if you want to install a single cat, as these headers are designed to match. Then you will need to address the fact that you no longer have connections for your 2 after-cat O2 sensors. The setup will not be emissions legal, since you will have deleted a cat or cats.

 

headers will, y-pipe will not. You have a dual cat car which has a different y-pipe

 

i just went through exactly what injuneer is talking about... a lot to consider, inj, you actually made it quite clear in the huge JBA header writeup you did here:
http://members.aol.com/InjuneerZZ/JBAHeadr.htm
as to what you need, process of removal and installation, and other odds and ends that you would never think of...

 

well this setup does not have cats...so shouldnt the y-pipe be the same for any year? Also i dont have emissions where i live so i dont have to worry about that. Do i need the air fitting meaning will it cause hesistation and what not? Also since there are no cats the headers should be fine right?

 

Yes... the Y-pipe you posted the link to will "work" on all years. You will have a mismatch when you try and connect it to the existing catback.

Since you didn't indicate up front that you were deleting the cats and didn't need them, I was trying to cover all the possibilities in a short concise statement. Sorry it didn't answer your question.

 

how bad of a mismatch? Is it diameter wise or is it forcing it in a direction to connect wise?

 

if its a bad mismatch then who has the cheapest y-pipe to fit stock manifolds?

 

The single-cat header Y-pipe will end at the front of the big hump in the passenger side floor. It is expecting to be welded to the single cat that normally resides under that hump in the 93-95 cars. Your dual-cat car has a different layout for the cats... only the passenger side cat resides under the hump, and the pipe from the drivers side runs past the cat and the "Y" is located after the cat. You will have a big gap between the end of the single-cat Y-pipe and the beginning of your stock (or preferably aftermarket, it you are adding headers) catback. I think they might make an adapter for this gap, called an "S-pipe".

 

who carries the "s-pipe" and how much do they run?

 

www.thunderracing.com i think has one, or www.summit.com, i have seen them for around 65$
