    I have just gone through the entire research loop trying to install a new cat for my 2005 Prius. I first started looking at aftermarket. I am not convinced. I tried to clean it out with Seafoam. Nothing yet. I finally decided I was not going to have any choice but to buy a new one for ~$2000 installed. The car is not worth that. So I think I am going to try a cat from a wrecked Prius. I can get a few here in town for around $140. I am willing to do that a few times if it will work, even for a few 10's of thousand miles. What I would like to know is how many differences there might be in the Gen 2 cats? I know I need one that is precisely for my 2005. But will a 2009 work? What are, if there are any, differences in the cats? I know there might be all kinds of legal problems that I have heard of. I am not worried about that. If it means saving nearly $2000, call me an outlaw.

    Also, I intend to buy the cat without the sensors. Or at least they will be clipped off the salvage car. Would there be any reason I should try to save the sensors from the new cat off the salvage car? It will mean a lot of extra work.

    BTW: I am certain it is the cat. I have gone through extensive testing with my mechanic to make sure it was not a sensor or some other problem.

    You can get a NEW Cat for $216 -cat only to $283 complete exhaust system at Rockauto.com
    I would suggest that you get both O2 sensors.
    Inquire on a shop which would install the CAT. I can tell you its not going to be a lot for such a simple install.

    I am looking for OEM. I have decided not to install an after market cat.

    If it's clogged cutting it apart and cleaning it with powerful enough air compressor will do the trick. Then just weld it together. If it's toast you don't have much to lose I guess. If you have VERY powerful compressor with high flow you don't even need to take it apart.
    But if something else is the problem you will have to get a new one, although I don't see the point of not wanting to go aftermarket. OEM is usually just the same stuff, but 5x the price.

    Yeah, I know. Not looking forward to the price. That is why I am trying to find out if any Gen 2 cat will work on my car so I can get it from a salvage vehicle. I have tried everything else. I am trying to find out what, if any changes there are in any of the Gen 2 cats.

    What was it about the aftermarket cats that left you unconvinced? I have heard good things about the
    Magnaflow 99205HM. Those should cost around $200 installed.

    I know. I have done enough research to make me just not want to go that route.

    Good news is my O2 sensor popped off with a light hammer tap to the wrench! After 220K, I was not looking forward to that. That makes me think of another question. When I put this O2 sensor back in, should I use a lubricant at all? If so, would there be any reason not to use a lithium grease or something that might help me keep this from freezing up? Not that it was difficult this time, but I have heard the stories of people that were not so lucky.

    You don't necessarily want to believe everything you read on the internet.

    In your position I think I'd much rather go with a brand new aftermarket than a used/salvaged OEM.

    I agree with The Electric Me, an aftermarket one installed for under $500 is really a good deal, plus you know everything will work.

    Yes no need for OEM except the California guys have to by law. The rest of us can get the cheaper replacements.

    some of the cheapo cats suck, and don't last long or fit right. I have seen some real hack job aftermarket cat installs. a very low mileage '09 cat from the junk yard would be an easy diy. some good penetrating spray, a new flange gasket and an o2 sensor socket would be all you need assuming you have a decent metric socket set and wrenches.

    Thanks so much. Do you know if all Gen 2 models match? I got some info earlier that they do, but I am trying to get as many opinions as possible. I'm
    hoping to pick up a 2006 tomorrow.BTW It has only 86K on it so I am hopeful

    I don't think there is any difference from year to year.

    They are all the same.2004-2009

    BTW: your old cat(s) are worth about $175 in scrap value

    Sounds great. I was not expecting the cat to be worth $175 or so in scrap. That would put me way ahead in the end. I am picking mine up today for $140. At least he did not say anything about a core. Even still, it is still worth it as long as I get some decent miles out of it.

    Just a follow up for future reference. I bought a cat from a salvaged Prius for $140 total. I did not need to return a core. I believe that was probably a great deal. But the others I found were in the $150-$250 range +core. I found a Prius with 86K on it so hopefully the cat works for a good while. I replaced mine with the new on and used the original gaskets. It was the easiest thing ever to replace. I was out from under my car in about 15-20 minutes with the old one out and the "new" one in. My gas mileage has gone up a couple mph, and my check engine light is off. I feel like it was totally worth the risk. And it is a CARB compliant, OEM part. Even if it only has 20-30K left in it, it will be worth doing again if I even keep the car that long.

    Sounds great. My 2004 has logged 214K miles and the cc is original.

    One of your posts says you logged 220K miles on your car, so the original cc lasted a good long time and if your engine remains in good condition, (appropriate air/fuel ratio control, and not burning excessive oil) there is no reason not to expect a similar life from the salvage cc.

    The use of such a cc is preferable to installing an aftermarket cc which is not CA-certified. The only issue remaining is whether use of a salvage cc is legal in your locale or not.

    Sure. I agree. I have it regularly maintained still so it is still in good shape I believe. I am under the opinion that it is really hard to mess up a Toyota engine. (Although my Honda Accord with 300K has been impossible to kill).
