I took my car initially to the dealership who told me that, although it seemed unusual for the age of my car, that I needed to replace 2 of the 3 catalytic converters for $3,400. I called Arie Nol for a quote and they explained to me why a car has them and that we should probably determine the REASON they would go bad this early before replacing. In the end, they found I had some bad valves which were causing wear on the cats. My cats were just at the threshhold of needing to be replaced but they recommended I replace the valves first or the new cats would just go bad again. In fact, by replacing the valves, the cats may fix themselves. Oh, and they'll replace the cats for half of what the dealership was going to charge me, if I still wish to do that. I'll never go back to Fox Honda, not even for an oil change. They do nothing but take your money without fixing the root of the problem.
