The o2 sensor wont affect performance much but you will see a drop in fuel mileage.
If the acceleration has taken a hit too, then the cat is probably clogged up. Maybe the o2 sensor caused it, so I wouldnt replace one without the other. I really dont get why this isnt a warranty item though. If the cat is part of the manifold I'd get it fixed soon before the cat breaks up and gets sucked back into the motor.
