Auto part guy saying that cat convertor he sells won’t fit my prius since my prius built in Japan?

    I’m a little confused because the description on the site says the part is a caddy convertor for Prius Gen 2..However when he ran my VIN he said the cat- convertor they sell won’t fit, even though it’s the right year, make and model.
    There is a disclaimer that says no Asian vehicles. I’m guessing that means the part won’t fit any Prius models made in Japan??

    Can anyone spread any light on this, and possibly point me in the direction of where to buy a cat converter that will fit my Prius?
    Thanks so much.

    Link to the part, or part number?

    Any Prius car you’re likely to encounter in the United States was made in Japan. (The Prius cars built in China and Thailand wouldn’t meet U.S. import regulations, and as I understand it, were sold only in those markets.)
    If the “Lake [A]rrowhead” in @Ian Simons's profile is the one in California, the only alternatives I know of that comply with CARB regulations, and thus could be assured of passing a Smog Check inspection, are the Toyota original and Magnaflow’s “California Grade” aftermarket part, both discussed in my December posting.

    I saw this on a post after searching the whole forum. It involves a Magnaflow part and another long part that needs to be welded together with the Magnaflow part. The guy said it cost him $300 and a welder. Do you know how this is done?

    The picture you show is the original Toyota exhaust system on the right (with two catalytic converters at the front end) next to an aftermarket "universal" converter. I assume that the owner of that prius was having the OE cats removed and replaced with the AM unit.

    If you live in CA or any other place that has similar emissions regs, then doing that kind of replacement will not pass inspection.

    For second-generation Prius cars that require CARB-approved catalytic converters, Magnaflow has two “California Grade” options: you can buy a complete exhaust pipe assembly (5631752, $2,950), which has both converters and is ready to bolt into place, just like Toyota’s original part, or you can buy the front (5631306, $1,981) and rear (5671305, $590) converters separately and weld them to your own pipes and flanges. Magnaflow describes those converters as “Universal,” but they are approved only for Prius models.

    The latter option is attractive if only one of the two converters needs replacement. It’s also good for muffler shops, which would prefer to cut, bend, and weld as necessary, rather than keep large, awkwardly-shaped assemblies in stock for many different models.
    That’s true, if you mean a replacement with an aftermarket converter without CARB approval. As long as both the front and rear catalytic converters are CARB-approved parts and properly installed, neither CARB nor a Smog Check inspector has any reason to care whether the exhaust pipe assembly was made in Magnaflow’s factory or by a local muffler shop.

    The manga is just one. How does the owner replace the two OE cats with one universal unit?
    I understand it might not pass, but is this best alternative other than purchasing the two oe cat(s) because it’s a Magnaflow?

    I had my cat converter stolen. I didn’t know there were two. When they stole the part, is it common for them to take both converters?

    Where can I buy one with all the parts on a budget that won’t trigger check engine light?

    Is Lake Arrowhead in California? You can buy on a budget that won't trigger CEL light, but in California you're more concerned with passing smog Carb inspection, even if it doesn't trigger check engine light.

    Can you send me a link to one that will fit Asian assembled vehicles?
