When catalytic converters fail they normally clog up with debris and block the flow of exhaust gas from getting out of the system. This causes extreme performance problems. In the extreme cases it will even prevent the car from starting at all. A clogged cat can get so hot that is will turn red. Park the car over any combustible material and you will have a fire. Can it cause damage to other engine parts? Maybe and maybe not. What it will do is waste fuel and cause your engine to struggle, just like it is being chocked to death. It cannot breath so it can perform as it should. Replace the converter if you know it is clogged.
