Based on that pic, that cat is becoming clogged from what looks like deposits. Misfires, and low engine output are in your near future. Rockauto has a bunch of aftermarket options. My cats on my 04 went around ~150K mi with a P0422 catalyst inefficiency. I think I paid $800/ea for OEM, and just did both "while you're in there" since they both had to come out anyways
