O2 Sensor

O2 Sensor
I have a new catalytic converter on order and am just wondering how many of the O2 sensors I need to replace along with the CAT to get peak performance and also to make sure that I don't damage the new CAT.
After doing some research I found that usually it is the downstream sensor that goes faulty and needs replacing, but I also read that it is good to change all of them.
Is it really necessary to replace ALL of them, I only ask cause they are around 50 bucks a pop!
Any advice would be greatly appreciatted.

I wouldn't replace any of them unless/until you get a code.
That being said, most manufacturers recommend changing all of them at 100,000 or 50,000 miles or 75,000 miles or take your pick to ensure optimum fuel milage.
