Well Ill probably end up keeping it for a rainy day.
and older euro and jap cars normally have lots more, like some places give $100 bucks for a used cat. factory toyotas, you take off the cat, sell it, go buy a low platinum new cat for halve what you got from the scrapper
And then go get a new cat when you need to pass smog or air care or what have you. It's not worth it.
