No, it will not trip a code on any of the pre-OBD-II cars. They don't have the 3rd O2 sensor after the cat to check the cat'* performance and report problems.
I was of the school that hollowed out the cat (busting the brick). These days, stock cats are less likely to plug up and better than stock flowing replacements are cheaper. So now I leave them in. Same reason the Air Injector pumps are no longer on cars, the cat technology got better and the ECM can alternate rich and lean mixture to keep the brick oxygenated without the need of an external pump putting air into the exhaust gas stream.
