2003 Chevy Tracker 2.5, LT upper bank catalytic converter

This compact SUV proved itself to be a fine ecnomical vehicle, good for making its way along any type of surface. Platform: CAMI (Suzuki)
2003 Chevy Tracker 2.5, LT upper bank catalytic converter
You can buy all four O2 sensors (Bosch) from O’Reilly Auto Parts or Autozone for about $300. A mechanic could swap all four in about one hour. So YOU do the math.
If you have to pay for all the the parts AND labor, I believe you are going to put $2000 into a $4000 vehicle.
It may be time to part ways with your beloved Tracker. 🙄
Let us know what the MILEAGE is on your Tracker.
If it’s more than 160k-180k miles, it’s going to turn into a money pit.
Example: Have you looked at your CV axle boots? Are they torn and leaking?
THAT is a $300 fix for EACH side.
It all starts to add up for an older vehicle. 🙄
OK so the final scenario is this. I took it to a mechanic today, and he stated it is definitely my catalytic converters. (upper/lower banks)
My vehicle has over 210,000 original miles. I bought it brand new back in July 2003. Now that I know what has to be replaced, how do I know which converter to buy if there are few options? It looks like my converters are EPA compliant. Please and thank you.
I have attached the options below, any and all recommendations are welcomed.
On a sidenote, I’m very grateful for everyone’s help on this forum. I am learning a lot, and really appreciate your time. 😀 I’m guessing right and left are equivalent to the upper and lower banks 🧐

You will notice that converters come in two flavors: EPA (49-state) compliant and CARB (California Air Resource Board) compliant. CARB converters are built to a higher standard and therefore more expensive. You can pass inspection with cheaper EPA compliant converters in NY. Also be aware that the PUP converters are only warm-up converters. The main catalytic converter is under the floorboard. It's condition is not monitored by the PCM. I do not know if NY tests the condition of that converter during an inspection. Usually if the PCM is not failing the I&M tests the car passses the emissions part of the inspection.

I don’t understand what PUP converters are. All I know is that the OBD scanner had P0420 and P0430. Will it matter if I use the carb compliant or should I just stick with the EPA compliant? Please and thank you.
Chevy calls the left and right manifold converters "PUP" converters. I don't know why. The EPA compliant converters will clear the P0420 and P0430 codes. All four O2 sensors are functionally identical. The reason for the different part numbers is that the downstream sensors have longer wires.
Can I install two different brands on the catalytic converters? One is a Walker, and the other is a Dorman. Not sure why the brands don’t have both sides. 🧐
You may have an issue!
According to RockAuto, NY requires a CARB compliant converter if you have a California LEV certified car which according to your under-hood sticker, you do. It looks like you may need the CARB compliant converter to pass inspection. Check with the inspection station to make sure.
Choice of converters now 🧐
