My car had the cat removed by a previous owner and that was able to get the CEL to stay off for 40k miles.
I don't like mods like that to be at all visible from the outside.
Usually what I do is cut a little peice of sheet metal and bend it into a cylinder and slip it around oxygen sensor to block most of the exhaust flow going into the sensor.
