06 problems

Has anyone had either of these problems. Whining noise gets louder as you go faster from the front of the car. And a code "catalyst efficiency below threshold bank 1" as far as I have found it has to do with the o2/catalyst sensor detecting a problem from bank 1. Car has 52k I don't think its under warranty anymore?

None, if I want a faster car I'll buy one.

Whining noise probably a wheel bearing. just replaced one on our '06. A friend turned me to Rockauto.com but you can get them locally too. not a bad job - need a gear puller too. No clue on problem #2...
