P0430 cel after y pipe install

Thinking that during the pipe work the guy might have jacked the downstream sensor, or it's breathing so well now that the old sensor is showing it's age. He did weld within an inch of the passenger side sensor. Either way I'm going to swap them out and hope that clears it up.

Some have said to stay away from certain brands of sensor. Which should I buy? Part #?

BTW, the y pipe swap IS impressive.

Ntk or denso is the OEM. Ive never personally experienced it but lots of people say these engines dont like bosch sensors and im not particularly keen on bosch products either so one of those first two mentioned will be great!
