Thanks for the response. I've been thinking about living with the code also, but it really drives me crazy when the cruise control doesn't work. I think I might replace the cat as soon as it warms up in Minnesota. I'll let you know if it fixes my problem.

Sorry to revive such an old thread. Did you ever find a solution to this problem on your 05? I have a 2005 Legacy 2.5i that is doing the exact same thing. It seems to run fine which makes me think the cats are fine, but I received the p0420 code, tried to do the mechanical fix, and ended up with e p2096. Please let me know what your final solution was.
