Need new catalitic converter, shall I just consider buying a different used car?

What is your question?

I need a new catalytic converter, 02 sensors, and y-pipe ... I have 122,000 miles on this Outback. Estimated cost to fix the 3 things above is like $3500!! I just spent like $2,000 on different things about 3 mos ago. I can't afford this, but can't afford a car payment now either. Don't know if I should consider getting a used car and let this one go or what?

How long has your 2003 Subaru Outback had this problem?

about 3 months
