smog pump etc.

my buddy has a 91 ford f250 with the 5 l engine that the pump is squeeling and the tubes at the rear of the engine that go to the rear of the heads and to the exhaust have rusted away . my question is since we are having trouble getting the new pipes etc, can the whole thing be taken off and if so what is the process and possible problems sam
