I only have that P0430 code so its not likely anything else.
I discovered that there are electronic devices that emulate a proper functioning downsteam sensor for a good CAT, but if a tailpipe sniffer test is used and they stick the probe in the passenger side exhaust they will likely detect excessive emissions.
However I could reinstall the downstream CATs and it would likely pass with the Electronic cheat (~$70).
But in the end its an inconvenience to reinstall the rear CATs every 2 years.
So it would be better to buy a replacement passenger side Header CAT.
I suppose I could buy a used one, which I prefer at this point to save some bucks, or I could bite the bullet and buy a new ~$1800 CAT.
Are there any other options I have overlooked?
Does anyone know of a used one for sale?
What is the best price/site for buying a new CAT?

The price on new cats are going to make your eyes water, so I would consider used cats out of a wreck. We have installed several sets of these for customers and had great results. Check the boneyards in your area for price and availability.
