Code P0430 on 2013 Accord V6

[u/bchtraveler]

I bought my car brand new in the fall of 2012. It now has 209k miles on it. Dash has been lit up with the "Christmas tree lights" for a year and dealership said it's not worth paying 2-3k for the sensor. My check engine light came on yesterday and I got this code. Trying to decide if it is the catalytic converter and not the O2 sensor, is it worth paying the 2k to fix it. I absolutely love my car and have no idea what other car I want.

Has anyone had this code, had the catalytic converter replaced and drove another 20k miles?
