What are these and can I get rid of them?

[gtcobra302]

I have no smog equipment or egr and I would really like the room I would gain by getting rid of these things. What are these things? Can I remove them?

Can't tell if the first pic is pointing to the 10 pin connectors or not. They're pretty important. The other parts (TAD and TAB) directs air from the heads to the H pipe.

I forget the name of the thing in the second pic but its a vacuum thingamabob for the egr system, if your not running an egr then you can probably get rid of it.

The first pic is the connectors where the fuel injector harness plugs into the main computer harnes.. so no you cannot get rid of them unless you want to do a carb conversion lol.
