    Im going to be replacing the driver side catalytic converter due to a P0430 code. Already tried switching the O2 sensors, fault stays on the same bank. After seeing how expensive OEM is I have decided to get one through Rock Auto. Hopefully this will help others in future searches for cat's as well. Basically I'm looking at 3 options, I decided to research the warranty for each cat because I think that speaks as to how confident they are about the longevity of the product. All 3 of these products come with a 5 year or 50k mile warranty on material.

    1. Eastern Catalytic - $223 - 50k mile catalyst performance
    2. Walker - $285 - 25k mile catalyst performance
    3. Bosal - $265 - 2 year unlimited mileage catalyst performance

    Based on my research it seems theres a clear winner with the Eastern Catalytic, being the cheapest and best warranty. But I wanted to check and see if anyone had any experience with any of these 3, or a converter that is similarly priced? I know Magnaflow is an option, but their warranty is only 25k miles and double the price.

    I've installed some Bosal exhaust systems and they rotted out in about three years. I'd don't have any experience with their catalytic converters but I'd assume they are not the best in longevity.

    Some scrapyards will pay good money for your old cat. I sold a couple when I did exhaust upgrades on past hotrods and got $50 to $100 if memory serves.

    The TRD exhaust is stainless steel. The Bosal aluminized steels systems were some of the fastest rusting I've ever seen. Within two years it looked like a part off the Titanic and by the third year came around the muffler rotted out.

    I'm surprised replacement cats don't last that long. How long do the stock cats last?

    Never heard of a cat wash, but after looking online it seems to have worked for some people. I will gladly spend a few hours of labor and some dish soap before spending hundreds of dollars. I bore scoped both cat's from the O2 sensor hole and i could clearly see through both cats, they were still white and no blockage. I may try taking them off one weekend and see if it helps.

    also @inwood customs

    Here you go. Background: the pertinent history appears on pages 1-3. I located the original technical paper and it is cited in post 31 on pg 3. Two inexpensive common chemicals are used: citric acid, and oxalic acid. The specific concentrations and these appear in posts 37, 38.

    I live in GA, but in an emissions county because im close to Atlanta. I had success using a Walker cat on a 94 Ranger and from what I've come up with they are probably the best bet of the cheap ones to buy for Tacoma's. I was able to clear my code and pass emissions, but the light has come back on and im tired of looking at it.

    I got $30 for mine.
    The guy looked up the numbers on the convertor and it fell under a category called "low grade import".
    I replaced mine with a dorman convertor from rockauto about 4 years ago and it's working fine but I don't think RA is selling dorman products anymore.

    I saw they had 1 Dorman left, but not on the bank that I need. Nice to hear its still holding up, I will keep that in consideration as well.

    I agree. Their mufflers are pretty cheap, mostly just use them old beaters where the customers dont really care and they just need something on there.

    The converter assemblies I've had pretty good luck with though. Again, i have not seen a ton of tacoma converter failures but, on other imports/german cars they've done the trick

    I went ahead and bought an OEM cat from a Toyota parts website, the driver side is only $480.50. I even called them to make sure it was the manifold/cat combo one and it was the right part# for my truck. For that price I will gladly spend a little more to get OEM quality, will be installing it myself next weekend. Im glad I looked at OEM ones because I just assumed reading from everyone on here that the cats were anywhere from 800-1200 a piece or something ridiculous.
