Can you hollow out a cat?

Is it possible to turn a catalytic converter into basically a straight through pipe? I can't find four inch pipe around here to replace my cat, much less the reducer fittings. If anyone has done this, can you tell me the process and the results. I know they do it on Harleys. One of the custom exhaust shops said that four inch electrical conduit can be used as exhaust pipe. Is this true?
