Actually, if you have th large factory OE cat, it can be worth nearly $120. There is a place in TX I think that buys them... send it to them and they will send you money.

For your information... a large cats... when fully processed properly into the three rare metals... are worth I am guessing around $300+. There is platinum which are worth $2150 an ounce, rhodium which are worth I think like $8000 per ounce and palladium... which are worth $500 an ounce.

So... how many ounce can you get out of it? A tiny fraction... and if you process many... you will get a ounce of each. That's why it is big business and why OE cats are so costly.

Aftermarket cats are so tiny and contain significantly alot less of the rare metals. Do a search online... Yahoo! and you will find all sorts of tidbits about cat converters.
