    Does anyone know the serial numbers on the cats for these cars? Not a biggie, just don't want to crawl under it. Apparently the market price at the recyclers is peaking right now so I want to get a price quote, but I need those serial numbers, one for each cat. IIRC, one is EA9?

    I see you are wanting to sell it for recycle. If it is good it may be worth mor to sell it as a working unit. People steal them frequently

    I have been trying to sell them to owners for years. It's a tough market. But I also hang on to them waiting for the precious metals market to go up. They have a book value to me of about $700. Based on the offers I'm getting on my ads from the recyclers, I'm thinking they're worth close to $900 now.

    Looking at records from when I scrapped one I'm seeing GD5 and EA6.

    This is indeed true. No one buys old, used catalytic converters, even when OE, and especially not when already stolen once.

    The true value of the three rare earth metals inside are only appreciated by special vendors that know/follow the value changes of those metals. They have risen astronomically last five years.

    The older versions on gen2 04-06 have a higher value due to almost excessive amounts of those precious elements.

    I do wonder if serial number is the correct term though, that term should indicate uniqueness. Likely more like version/model identifier, you just will have to crawl and likely use some Rockwell/scotcbrite to rub it to visibility. ;)

    No one would buy them stolen for re-use because the thieves cut the cat off behind the exhaust manifold flange and again in front of the resonator. That front cut would be hard to weld back. But yeah, no one buys them much at all - I've only sold 3 in 4 years. I talk anyone in a non-CARB state out of buying, and I tell the CARB state owners to have two exhausts - one CARB-compliant for when you have inspections, and a second, non-CARB for your daily driver.
