I'm not worried about the environmental/legal issues. I'm not too worried about the cel being on all the time. Do I need to do anything to protect my engine at this point? Thanks!

If you're not worried about the check engine light (which will more than likely turn on since the 02 sensor will be receiving an excess amount of exhaust reaching it now) or environmental considerations, then removing the cat won't cause any harm to your engine. Some people even believe that driving without a catalytic converter allows the engine to breathe better and utilize more of its horsepower. Be warned though, there are typically laws in place that say a car must have a catalytic converter.
