I hate mechanics that try to find fault instead of finding solutions, the difference in OEM price is well worth the modification needed to make this work.

I just bought one from eBay for my 06 Prius and it was way better quality. This video was made 2 yrs ago, so I suspect the quality has improved. The flange looks like the original one. Payd $104+tax.. fit perfect. Worth every penny.

You are joking, right? Ever hear of a pipe expander? And lead gaskets are MADE to crush fit. You probably should not have ground off the welds. It would seal better sitting higher. For the $1500 difference between ebay and oem, I can deal with the gasket issues. And hire a mechanic who can improvise....

At least he didnt say, "wont fit, buy oem" yes it needs to be modified, but sounds like this guy is willing and able to make this work for his customer.

I'm not even a mechanic but I could fettle around with this to get it to work. You could use a clamp to reduce the size of the existing pipe and/or use a pipe expander on the Cat end to make it fit. On the other end that gasket is soft and made of lead, you could easily manipulate it to fit and create a good seal. Obviously if insurance was paying for it I would insist on OEM parts but if you have an old car not worth much I'd be looking at getting a $100 Cat.

Thanks for letting us know about this. As for people that go out and Steal catalytic I believe that they should be charged to the max that the law wall law and it involves jail time so be it

Very educational video regarding Catalytic converter. As I decided to replace my catalytic converter after doing some homework, I now know a few things which I never knew before. Thank you

Great Man,, thank you for your kindness words. We need more mechanic like you 🙏🙏

A $200 Flux welder and a pipe expander or just using bigger couplings may be cheaper than an oem cat too

Yep, they are of poor quality welds, but, you get what you pay for. I bought two sets of exact replacement cats and y pipe off Amazon for less than $700 saving about $900 on oem, I did this knowing full well that I would have to do modifications to them, being a mig welder of 25 years helps. If anyone buying these cheap cats isn’t a welder or know one that can do the mods they should take their vehicle to a muffler shop in the first place. But $700 and a few hours of my time isn’t a big deal, whereas saving $900 is. Btw it passed inspection, so they do work.

$5,000 reward for the reporting and capture of a illegal recycle centers, there is no honor among Thieves they will report on themselves, thieves are like cockroaches and will turn in their own mother for a buck, it's as simple as that, problem solved

I've made a similar one to this work on a Civic, the flange had the welds just like that. I just replaced the entire gasket with copper RTV, haha. It was a cheap car that needed a cheap fix and it held together for as long as I had the car so I was happy. I'm guessing that wouldn't be a recommended method for most people though 😂

Great information! Thank you for pointing this out. Unfortunately I just received mine today but it's for a 2007 Toyota Tundra and the gaskets are different. They look like a simple ring that goes over a small extended piece of the pipe at both ends. I'm hoping like hell it's not going to give me too much grief. Cheers. Oh, by the way, I simply couldn't afford $800 plus CAD so the $133 CAD fit my budget. Hoping I can get it installed for less than $600!!!

Dealing with that aftermarket piece of crap is like being victimized all over again

Thanks for sharing. My mechanic has pipe expanders , welders, grinders and skills to make it work. That’s because he has years of experience.

Definitely helped. Thanks . I will definitely look out for this. And the stealing cats, that’s just disgusting. Maybe we can suggest to the Manufacturers to design some type of alert or sensor that will alert the owners or maybe the police or somebody that these guys are taking the cats just as a suggestion

I have an idea about stopping catalytics converter thieves, once caught lets only cut one finger off n so on should they continue stealing cats.

Dude thanks for video I wish it was published earlier before I bought mine

There's always a reason why its cheaper, great video thank you.

Thanks for the advice on a Catalic Converter for Honda Element 👍 really good tip about it to not buy cheap crap from Ebay & Amazon parts on this case of Catalic.

going to go check my hot deal right now, thanks for this video, hope mine is not a hot mess like this one was

Seems like you could get this to work.

Thank you for taking the time to make this video. It was very useful and informative

That's really the only problem? You can adapt the rear and you can cut off the front and weld on the old one. Adapt

I will cut the flange and weld the old one

If the flange side bolts on could you not use some type of gasket shaped like the flange? Something like that came with an aftermarket cat that I purchased. Perhaps a heat resistant liquid gasket and then heat resistant epoxy as a double barrier around the edges

Thanks for the PSA but I think I'll buy this and a welder. Still a lot cheaper than OEM

So I finally bit the bullet and got a new cat for my 07 Nissan Sentra 2.0. This time it's CA regulated like it says on the sticker. It's been on for two days now. I have a question, is there a break in period before the good mpgs start to kick in? My SED light went off which is a blessing but it seems like my mpg's went down a little. Was there any special instructions that I was supposed to follow? My car has a direct fit so all I did was take it off, put on the new one and went about my way. TIA 🤔

Hi, any luck this would be a good choice for my smart fortwo 2008 petrol : BM91590H by BM Catalysts. My original CAT rusted so bad that it broke

Man, that's messed up the cats getting stolen. And whoever made that flange didn't know what they're doing. I bought one for my S10 of Amazon but I knew I would have to cut and weld into a pretty straight piece of pipe. Plus I own my own shop, this old S!0 has 220k and failed emissions. Amazon sold me universal marked damage because of the package for $30. Passed emissions next day.

i have the exact same cat. the front works as is. the gasket will seal whn you tighten it down. those caskets are soft and will conform. the rear i did cut and weld. cat works no codes.

Wow. Thanks for the info. I was going to buy on Ebay. When I saw this video. I change my mind. Good job on the video

Do cng vehicles need them? If stolen stolen how can i cheaply make it quiet quiet and stop backfireing and be able to go fast again?

Would you say we are obligated to change a catyltic converter? Also, if it's failing.. would that make a huge muffler noise?

Question - are there 2 catalytic converters on that pipe.??? Why are there two.???

There's a sleeve that connects those 2 ends at the back cut. Literally slips over the two halves and tightens with a clamp on each side. It's a rolled metal tube that squeezes tight.

is this the same for a 2001 toyota sequoia? or is this for the prius only??

Did he put it on? If not the grinding of the welds probably made it so it couldn't be returned

Kit I bought front end fits perfectly 👍

Don't charge too much for 'em and thieves will stop stealing 'em.

Enlarge the rear pipe with a stretcher cut and weld the old mount on the other end? Fixed

Yeah someone still mine, and thanks I was ganna try to get a chipper one but watching this..🤔 I'll go to the auto parts 👍🏿

I bought 3 converters off of ebay (my car takes 3) fit alright but all the nuts they sent didn't fit the bolts welded to the cats.

Hey hey buddy I just had my catalytic converter stolen today I want to thank you for the Post because I was just about to buy one from the internet and go on the cheap side thank you

Yup had ours stolen off my sons 2002 Honda CR-V. he’s a poor student with rising costs on everything including school. The car was in mint condition and safe for him to drive. I would of given them 200-$300 not to cut it out. Oem is way to expensive , can we run straight pipe bypass the a CAT, We live in a place where old vehicles are not inspected annually, or any other alternative . Where he works , it’s a dark place and 100% sure it will happen again . Seems like a new black market industry now of days .

thank you for this. one thing though, this is a 2nd gen prius. the 1st gen is 1999-2003

If I find someone stealing a cat I’ll just twist the handle to the Jack and let the car crush them. They deserve it tbh.

What do you recommend to buy for a gen2 prius? I Can’t seem t get a straight answer.

I currently have the exact problem he's talking about. I bought the cat on eBay, had it installed and I could smell the gasses coming into the car as I drive. i went to a muffler shop to have the back side of the pipe welded. I though my problem was solved but I can still smell the gasses. my suspicion was a bad doughnut gasket. I removed the bolts to check the gasket but it was fine , but I did noticed there was smoke marks around it where the gasses leak. I have not removed the cat since it's welded on but I think the cat has a bad flange. this video explains exactly what the problem is. Thanks

muffler shops have tubing expanders they can use

cut off the bad designed flange and weld on the original designed flange. Other thought I had. I use Permatex ultra copper to seal up exhaust, it works well enough. Maybe that will seal it, needs to cure overnight. And you can buy wide band clamps to but joint exhaust pipes together that don't slide together, they also work well.

They’re literally made mass produced in an assembly line kinda style, they’re also $100 to $250 and from EBay/ Amazon, what’d ya expect? There’s several that even state “further modifications maybe needed”.

I was wondering if you could help me figure out how much a catalytic converter should cost for a vw passat 2014. Im pretty dumb when it comes to car stuff and I see prices online anywhere from 250$-1500$. Im so confused. Thank you

Thank you for your video , Quick question, does the Catholic convert to give the press a better sound?

420 code blaze it ☄️💨

Thanks for the imput!!! Mine got stolen 11/5/20 in plain daylight at Target.

brother,thank you very much.awesome video.

This gaskets soft and take shape

As a person who works with exhaust systems I will only install Walker Ultra, Dorman, or Magnaflow catalytic converters. The others will just fail even if they fit properly.

My 01 Honda Accord cat just got stolen this morning. Do you have any recommend websites where I can buy a good aftermarket cat?

Hey, sorry to see it happen to anyone. what brand cat is that?

I'm seeing these cats don't have connections for 02 sensors. I'm really confused now.

seems like I am good then. I am going to get one from Ebay for my ls swap. I am building the exhaust anyway. So it seems like we are good to go.

I just got one for my Honda and it fit perfect …car still loud tho but not as bad I think it’s due to the theft trying to cut it off at first when it’s a bolt on

Wish I seen this before I did buy mine

What about the direct fit cat converters

3:15 problem solved, use a normal gasket design. there are many exhaust gaskets from other vehicles that will fit that flange and go in between the two pieces rather than inside it. all in all any mechanic shop that isn't just your neighbor bubba's house garage has more than enough tools to easily install that. like 30 minutes tops, no problems whatsoever. the real problem is that since it is just a few hundred dollars, it's not using the rare metals that are found in an oem cat, it's using a ceramic substrate with anyhwere from 0 to very little (barely above 0) of the catalysts (precious metals that heat up and catalyze unburnt fuel's transition to it's fully combusted products) needed to make it work properly. a *good* shop would not only have no problems, but no complaints installing one of these. they would however caution you that it will not function XD

What brand was the Cat in this Video? Last week some Bastard/Bastardette sawzalled the 2 Cats off my Cadillac

I live in california and 5 days ago they stole my catalyc converter.. I was driving my 2009 prius without catalyc converter..drove it for 4 miles and it worked then I drove it back home and now it does not go into gear. It turns on but does not go into gear. The red triangle came on with exclamation point while driving it back home and then a few min after it did not respond anymore. I parked it a block away from home cause I could not make it home. My insurance is towing it tomorrow to a shop so they can fix it..but now it has an issue with not going into gear..do u think that's because it does not have catalyc converter? Car was running great before it got stolen..no issues at all..I wonder if I messed it up or the prius is doing it on purpose just to be safe since it does not have the cat?

Are there solutions that you can put into your car to make the metals that are in the catalytic converters worthless? If that can be done it would make stealing them not worth it. The other option would be to have real time tracking when it gets stolen.

What is the best catalytic converters for California compliance 8.1 Chevy engine 01 f... them thieves?

Exhaust pipe stretcher???

The problem is they brought the car to you instead of the exaughts shop who will weld it on. They can also just cut off the end and weld the original flange onto the aftermarket cat. Probably charge $300

appreciate you sharing this info thanks!

My good folks at orielys helped me find a gasket to fit my jeep tj DNA muffler and told me about muffler cement/putty as a backup for a misaligned seal

Me too! Wish I saw this b4 I got one. 🤦🏾‍♂️

You didn’t mention the name of the brand. Is this one of the Evan Fischer ones or just some generic, obscure brand? I need to know because I’m about to buy 2….

For an expert, I’m surprised you don’t know about exhaust pipe expansion tool. A tenth of an inch is Nothing. And at the fore end, put your grinder and hammer to work and Make that shit work.

Tail Pipe expander for the rear, and clamp down the front, gasket will form to fit

What was the brand and the ebay shop name?

Ahh the old Cat problems! I purchased mine from eBay and it's spot on inch for inch with no problems! And yes dirt cheaper! As far as theft! next time tell them to GET AN ALARM! ITS 2021 FOR CRYING OUT..On eBay It's very informative to do research on companies before you purchase! READ READ READ the positive and negative reviews like it's nobody's business. Because most of the time negative reviews are from fussy costumers that didn't get their product fast enough, or packaging was horrible blah blah. having nothing to do with the functioning of that item most of the time. But If everything pans out then take that gamble..we all do.. some successful some not..I wouldn't totally abandon a helpful market because one person got screwed. That's the risk you take! Yes indeed that was sloppy work here! But totally fixable..most mechanic's don't want to do anything"Extra" but want simple, fast, and precise work all the time. Being a mechanic you will run into more headaches than smooth sailing. If you're deep in the the game then you should know this. And if your in the business it's good to put your big boy pants on and get the job done.. period!!

too late for me, I bought two of catalytic converter bank 1 and bank 2 for my 10 3.5L V6 Honda Accord. The bank 1 fortunately fits but the other does not. I am mad as hell right now I wish I should have seen this video before purchasing my catalytic converters.

I replaced mine with one similar to that, fit right on

can these be grinded to fit better

I never bolt! Weld it all together!

Strange. I bought one of those for my 2008 Prius and the muffler shop installed it in 20 minutes. No complaints!

What happens if the content of the cat converter is scrapped out? How does that affect the car?

thanks for the video. is this an AP-Eastern, or, a Walker product?

Will it seal if you spit on it?

Will this cause a slight misfire??

I can't believe the guy before me would use a exhaust pipe expansion tool, when you buy something you shouldn't have to alter or manufacture parts to make it work. This is the crap that comes from oversees.

Run a test pipe for the rest of the year, swap the cat in for smog. When they see it's a straight pipe they won't steal it.

there are tool to expend pipes to fit each others , flenge side you have to grind it little bit to fit , seem to be you just want to be too easy for you .

Pipe diameter adapters?

my cats with o2 sensor was cut off of my 2000 ford crown victoria police interceptor before i bought it now what?

My son has a 2008 Honda Accord LX with a 420 code. How would we know which catalytic converter to get? I read somewhere that it's two. Is that correct? If so, how would we know which one to replace? I've seen some on eBay for less are these aftermarket brands and would they work as well? Any information you can provide that will help us will be greatly appreciated.

People stole my friends brand new Dodge Ram Pick up’s Cat. Car was less than a week old.

I bought some for my 2006 Toyota tundra 4.7. And my check engine keeps coming on. 😢

I got an aftermarket one installed for around $260 with warranty.. about 2 months later , which is now , its making a loud annoying noise.. do you think theyll honor the warrantt , or only when the check engine light comes on ? I knew i shouldve just spent the $1,000 for the better job smh

I popped some rtv on both sides of the gasket. I've got a good 3 years out if it. I just passed my emissions test 2 weeks ago.
