I am only speaking for myself but sure if the car is EOL why not. A working cat puts a lot of heat into the front part of the exhaust system and provides some extended life over a comparable system without one. Then there is the environmental angle but that's another story but IMO its not bad having the car pollute less.

I agree with you there as well. Ideally we would do all repairs in acceptable manners but many people find short cuts.
