It is part of emmision (smog) control. It is used on my 85 Eldo to inject air to either exhaust manifold or to the cat converter (depending on the driving conditions). That added air makes the exhaust cleaner by helping the cat converter in burning leftover fuel.
You can get rid of it but your car will most likely fail emmisions iinspection (if there is one in your state).
