    My 2007 Prius has been throwing a P0420 for some time, so I'm not surprised the cat needs to be replaced. Toyota wants $2500 for the job. Meineke is around $700.00.

    But I can find multiple websites that advertise "2004-2009 Toyota Prius 1.5L Catalytic Converter Direct Fit" for around $104 to $116.00.

    Are these worth anything? Are they Chinese garbage? Or will they do the job just fine and the other shops are just charging ten prices for the same kind of thing?

    Thanks for your time!

    Since you’re not in CA or NY, they could work.

    Just depends on how long you want the fix to last.

    Good luck and keep us posted (y).

    I did this with the help of a welder in CA for $300 IMG_6424.jpg the four bolts are easy enough to remove and take the center section of exhaust in to your favorite welder to splice in the replacement. IMG_6388.jpg

    That would never pass in Cali. But will probably work fine. Cost for cats is directly related to the amount of exotic metals in the catalyst. The one you got is a generic one size fits many. A 420 code does not necessarily mean the cat is bad, btw. It also does not equal the "go private" price of a share of Tesla.

    This explain the big price difference of OEM vs aftermarket. And why I remember someone's universal fit only lasting a year.

    Warranty is the other equation too. CARB certified catalytic converters require testing to prove that they are as effective as OEM, thus being certified as CARB compliant. AND, aftermarket catalytic converters must have a MINIMUM warranty of 5yr/50,000miles. Aftermarket ones only seem to have a 1yr warranty.

    Thus the price difference in catalytic converters. Low cost = shorter longevity due to less precious metals, and no testing certification.

    BTW, if the engine is burning A LOT of oil, this will kill all catalytic converters, quickly.

    This one is specifically Cali approved. It does fix the problem and actually has more platinum coated ceramic in it than the originals. The OEM is the entire mid section $1900. Which includes an additional cat converter past the second O2 sensor.

    I bought the cheap Ebay version for $100, you have to cut your exhaust just past the 2nd cat and bolt it on. It turned off the CEL for me and I really don't expect it to last for the price how much platinum in the cells could you expect once you factor in the cost of the pipe, hardware, welding, etc. But my car burns a lot of oil so once this cat becomes clogged at least I can take it off the car and punch the honeycomb out and let the exhaust free flow.

    The deed is done, I scored a direct fit cat from Arctic Exhaust on eBay for $104, my local mechanic installed it for $167. A lot cheaper than the $2600 Toyota wanted, cleared my code, and will last long enough for my needs. No emissions tests up here in Maine. Thanks for all the input!
