Cobbled together exhaust systems put more stress on the o2 sensors and more stress on the catalytic converter because it messes with the exhaust flow, there are plenty of cars out there with 300,000 miles on them that have the original catalytic converter.
If your check engine light is on with a cat code, removing it isn't going to change anything unless you replace it with a working part, replacing it with a working part is only going to last if it's not under abnormal stress.
