Got these codes today. Anyone have any experience with them? Is it pretty much going to be changing out the cats? If so, any idea of cost?

When they're by themselves, those codes always mean dying cats. When they're pending it means they didn't reoccur on a second trip, so it's likely the cats are "on the edge" and you have some time before they get really bad. Someone else will have to help you with the cost, I'm a Nissan tech and don't see Infinitis every day.
