So my CEL came on recently, and had it read at autozone, then again at the dealership, and both say its a code that indicates my cats are going bad. my vehicle is a 2004 obw 5spd, with EJ259 motor, and from what I know my model has far more expensive cats than earlier 2000's outbacks. 120k seems early to me for the cats to go, having friends with 200k on origional cats. the cost of new cats seems to be too astroniomical to me based on the book value of the car...any thoughts? thanks!
