Wierd CEL issue.
So I had a hole in my exhaust that I got fixed yesterday. I never got a CEL from it but thought maybe cuz of where it was on the exhaust?
Anyways, driving the car for 30 mins AFTER I got it fixed the CEL came on. I checked it and it gave me a Cat code, that it wasnt running properly/efficiently or whatever. Which is strange because I shoulda had that code when I had the hole, not after. I cleared it and it hasnt come on during my drive to work today.
Should it be something of concern? Should I be worried that my ECU isint functioning properly or something?

Nope. Your ECU knows that cat is bad when reading from pre cat O2 sensor are the same as readings from post cat O2 sensor. Before when you had a leak reading was different between sensors even with dead cat, now with cat patched up reading are the same. Blink. Blink. MIL
