So what is the link to the one you purchased? Cheap fake cats on ebay don't last long, before check engine light comes on. especially on hybrids where they turn on and off many times in a drive. How many miles and years do you have, who installed it, how was the swivel flange and the pipe size to attach in the rear?

[@brandonrestivo9181]

Curious how your eBay cat is functioning after a year.

[@robbflynn4325]

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.

[@subtledriver]

It will leak, and cause it to run rich or throw codes from the torn lead seal and air leak and in a few months you will get a p0420 code cause the cat is not designed for an engine that turns off and on so many times.

[@subtledriver]

The original gasket is designed to seal with spring loading and be able to pivot/swivel with the engine movement to prevent the exhaust manifold from getting stress cracks. The pipe was physically equal with stock, and If the add states "bolt-on", it should bolt-on without need of extra tools and cutting off a warped flange. The other bolt-on cat's ive installed actually do bolt-up and have quality sealing without warped flanges and work like factory. thanks for the comment.

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 😂

[@mediasmoker]

That was my first thought...why not just run a thick bead of Permatex around the joint? I've even heard of guys using furnace cement for exhaust leaks....and if it has a big hole or void, mix it up well with some fiberglass wall insulation. I get the point he's trying to make, but sometimes the rent needs to get paid, kids need to be fed or grandma needs her meds...and that car needs to get to work one way or another.

[@bluethunder1951]

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.

[@KRColson]

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!!!

[@subtledriver]

Good luck! Even if it fits well,,, usually the lower end cat will fail sooner than the expensive one because it has cheaper materials. I would make sure your primary o2 and maf sensor is working great, along with no air leaks and no misfires and thermostat working good. Any of these basic problems will ruin a cat very short time.

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

[@ClintonC1991]

@@budthechud3408 sorry I didn't. I decided to leave the cats off

[@johnc3730]

Why the mechanic asked me if the front cat or the rear one is problem when I called him for repair? I only know there is one cat in the rear. Thank you.

Theft is for someone who is suicidal. They should seriously re consider and seek help immediately. There won't be a next time... Facts jack

[@djdonbentley2141]

When you buy those types of Assembly , almost always you realize it will involve step up and step down spacers and metal size bushing adapters . Unfortunately , if it needs these , then it is one that also needs welding to bond the joints . It sucks .

[@joancostello]

This Catalytic Converter will work if this man comes with common sense, get a grinder and gaskets and make it work..Simple job

[@subtledriver]

I'll send the common sense jobs your way. Doesn't pay enough for me to bother with it. I'll stick with the parts that actually fit

[@PeterDrinnan]

Always read the reviews before you buy.

[@Seyer1955]

You already have the solution! Just need a little work. It will work.

[@2bnax]

ARE THERE ANY QUALITY AFTERMARKET CATALYTIC CONV. FOR 2014 SENTRAS?? GREAT VIDEO! I DEFINITELY DON'T WANT ANY UNFORSEEN PROBLEMS , I'M NOT A MECHANIC BUT WILLING TO TRY REPLACING THE CAT WITHOUT ADDED COMPLICATIONS!! WHAT 'S THE MATTER WITH THOSE HATERS??? THANKS FOR THE HELPFUL VIDEO, GOD BLESS YOU!!!

[@adirectconflict]

VIDEO FAIL: Never have I seen more incorrect information provided in one video. 1. A step down adapter ring works perfectly to connect this cat converter to the rear pipe. 2. Once installed the RUBBER flange WILL seal completely. This guy is not a "mechanic". "Mechanics" are honest and truthful. Oh, and telling people to go 10mph over the speed limit is not only stupid, it's promoting illegal activity.

[@marblox9300]

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

[@wizard3z868]

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

[@yopp3.016]

Exhaust pipe stretcher???

[@scientist100]

Yeah, and cut a slit and weld it later

[@FJB8885]

You mentioning to the Prius owners to move over out of the fast lane was right on. Thank you so much for saying, hopefully some of them will understand it and follow your advice. Smart folks know that part was made in China and the world's convinced that "all" Asian people are smart and they welded that crap together and said we're smart too. I would imagine there are proprietary design concerns that the Chinese couldn't make it "exact fit" at the cheapest price. Always use original equipment.

[@futbol1972]

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?

[@amazoidal]

It's just a coincidence. The cat controls nothing but a check engine light.

[@futbol1972]

You were right I checked 12v battery and it was reading 11.7 or something like that so I replaced it and now everything back to normal.

[@futbol1972]

@Randall Glatt here in califorbia because of tje emissions laws there is no way around it. I bought the cat from dealer:( can't even use an use one from another prius has to be brand new from dealer. Paid Alitalia over $3000 You are lucky cause in Vegas u can install an aftermarket for a couple of 100 bucks.

[@futbol1972]

@Randall Glatt no problem

[@IkarosCanFly]

I got a cat from Amazon for my 03 Honda CRV and I could never get rid of a P0420 code (cat efficiency below threshold). Cheap cats will throw codes. Didn't matter why O2 sensors I got.

[@gueroburban4989]

This is happening to my 2007 suburban got those codes after I got these cats of ebay well complete y pipe and a slight misfire now

[@elvism684]

I bought a Walker direct fit for a 2002 CRV EPA. That was sometime last year. No check engine light after , passed emissions. The shop my mom took it to cut the flanges and welded it on. She said they didn’t even try to bolt it on not sure of direct fitment though.

[@Mocconagames]

the biggest issue is that this cats will not still long, it's for 1-1.5 years and they will light the check and you will feel dirt on exhaust.

[@stoneyislandranch9783]

The amount of money they cost new is well worth having to do a few alterations.. swell the pipe on the end.. weld the flange..solved.. probably saved a couple thousand bucks

[@ratagris21]

I hear that the magna flows and Walker complete assemblies seem to be the way to go.

[@TheCybertiger9]

My car Magnaflow = $600 on sale (Hottexhaust) Walker = $430 (Amazon)

[@user-zs1tp8px4s]

Technician versus parts changer. I see no issue with the cat once you sleeve the exhaust or weld and weld on the original flange. Add labor to the ticket and get the car off the lift. Flat raters would have already had this done

[@subtledriver]

This video is to show what a "bolt-on" cheap cat experience is. Not to show what a mechanic with a chop saw, pipe expander and welder can do with cheap junk.

[@subtledriver]

The part was welded on with factory flange, I just wanted to show how things aren't manufactured properly, so buyer beware.

[@luisduran2303]

I thought that when he said whoever you are F U😂. But no, he was polite.

[@8peterp]

mine just got stolen from Prius ,was replaced by insurance before for previous owner ,thought it's not original ,sadly was. would not buy original ever again ,man up or not ,i would jut dremel the c* out of this amazon one til seals. here in Europe Prius is a pretty fast car anyway ,we buy it because low tax

[@slickdick8706]

If I were buying a new cat converter after somebody stealing my Cat, Then I would buy a Magnaflow Carb Compliant Cat Converter from O'REILLY'S..... Maybe AutoZone then purchase the fitting adapters separately.... Then finally, I'll let the Muffler guy figure out on getting the set together. There's NO WAY in hell I'm spending more than $500 to replace the Cat Converter, NO WAY. There's mechanics out there that would con U out of $1,000 to $6,000 to replace the exhaust system. It's NOT necessary to replace the entire tailpipe system. I'm like hey, All I need is the new Cat Converter installed on my car and it DOESN'T get any BASIC then that.

[@joepublic2894]

I got to say,you miss led me in the beginning .I say that because if your any kind of mechanic YOU SHOULD KNOW about a pipe expanding tool.they cost 30 dollars and open a 2 inch pipe to 2 1/4 with just a few turns of the wrench.I don't say this to embarrass you ,but hopefully to correct the info you put out,I wrenched for years along time ago,before cats were on cars and i even have one a pipe ex pander,in my box at home.You don't need to weld it ,if you have the tool.but i also agree welding pipe is the best way to be leak free.

[@travispratt6327]

Someone needs to figure out a better way to filter the exhaust than superheating precious metals, that’s the only thing that will actually stop it.

[@theroyalcrownedtiger2946]

Replace the new flange with the original one, and use a pipe adapter to the pipe on the back of the cat, make it fit.

[@Lilmiket1000]

I would have sent that junk back. I got mine from Amazon but mine is made closer to the factory one. So everything bolted up very nicely with no issues. The only problem is that every so often if I have to floor the gas to merge onto the highway the check engine light will be on on the next start cycle. After a few cycles it goes back off on its own. But Always comes back anytime I have to accelerate too hard. I got so tired of this bs that I started looking for a factory one. But I can't find anything under 3k. I barely paid that much for the whole car so that's out of the question. On my first gen prius I was able to find a factory Cat for 900. I was really hoping to find something around that price for this 2nd gen.
