If you aren't having issues, leave it alone. The down stream doesn't do anything for the car, it just checks that the cat is OK. If you are getting cat codes, see if the cat rattles, if not, try the new O2 sensor. If the numbers match, it should be OK. I've used Walker's in other cars with no problems.

Besides that anything but OEM blue box Volvo or a Bosch could make things worse
These cars do not like aftermarket 02 sensors

I agree with JRL - O2 sensors and MAF sensors you have to go OEM/Bosch or the car will complain. Unfortunate but simple fact. I wouldn't spend any time on it.
