This against the back of the motor I thought it was the egr since all the lines from the exhaust and air pump are running to and from it. I have an 2002 Z-28. Maybe someone else can make heads or tails of it.

Thats is the Air pipe valve, you probably have one of them on the other side too. The Air pipes pass air from the pump in the front wing to make the emmusiones seem cleaner on start up.
The EGR is at the front of the Engine, if you have a 2001 or 2002 you wont have an EGR. When looking at the engine from the front, the EGR is on the left and two main pipes come from it, one to the top of the intake the other to your exhaust manifold.

That's the air check valve, don't know why you don't have one on the passenger side - should be right above the #4 coil pack. Here's a link to remove the AIR system: http://www.ls1camaro.net/sections.ph...ticle&artid=70

When he is saying "I just have one", I beleive he's talking about "the spaceship looking thing".
The check valves are directly upstream of where the AIR tubes bolt to the headers, there ARE 1 of those on each side.
The "spaceship thing" will need to be removed when you yank the system. You'll need to make some blockoff plates for the exhaust. You can unbolt the flap under/behind the driverside foglight and drop the AIR pump out the bottom after you unbolt/unplug it.
The big black thing in the front of this picture is the "check valve"..
The thing WAAAAAAAAAY in the back is commonly referred to as "that spaceship thing", and is pictured here. That vacuum line coming out of the top needs to be plugged as well.
The "spaceship" thing has a clip that slides into a slot on the manifold. You have to depress the clip to let it pop out of the slot. It's cliped in there the same way as the gas tank vent solenoid thing (beside the #1 injector) is fastened, look at it for reference.
