I have no idea if any such product exists, but right now I'd love to get my hands on one if I could. I just spend $930 on getting one replaced (price includes gaskets that were needed as well), and he warned me that there was another one on the Sienna, implying that that might need to be replaced as well at some point in the future.
I trust this guy--that's not the issue. I'm just wondering--is there something like techron that I can pour into the gas tank, that will help clean out the catalytic converter?
