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....
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'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.
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 ''average'' person wouldn't buy it online and try to do it himself in the first place.. any shop can make this pipe work with basic mechanic skills.

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.
It was installed after I cut off the flange and welded on a factory flange, then welded the back end since the pipes didn't slide over as advertised either.... the cat only lasted about 2 oil changes before getting check engine code for bad cat. Not worth it...
All he need to do is grind that inner sealing piece flush then he can weld the outer flange fully from the outside and walah 10 bucks in grinding wheels and 10 bucks for 2lb of ideal e71tgs if your doing it with cheap wire welder 10 bucks in gaskets.

The gasket will conform to the shape of the aftermarket flange and spin on the flat factory side of the flange. It will still provide the flex necessary, I think you just wanted to tell the people to buy another cat
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 😂
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.
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 would of grinded down that seal to fit the flange or reuse the old seal if I could.when you tighten the whole thing up that seal will conform to any deformities.
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
exactly what i do with almost every aftermarket part i get. merge as much oem to it as possible. but i do get his point; people are paying money for "direct fit" now he has to do extra work. so the client loses money on both buying the part and letting it get installed
So you pay less for "direct fit" and end up paying shop 100-170/hr to make it work.. Yeah, that's it. Might as well just buy an OEM CAT and have a longer lasting CAT. Which is what his point in video is.
LoL don't waste your time with this. Make my job easy and go spend 1500 or more on a factory Cat. A new Gasket will crush the the needed fitment. Also on the tail end, it would be better to weld the factory end on anyways. And personally all this Catalytic Converter bs is just that. Feel good nonsense for people that think they are saving the environment. But everything they buy is wrapped in some form of plastic that they throw away.
You take it to a muffler shop they specialize in modifications and making things work. I ordered mine from ebay, went to the muffler shop I trust I was out within 45 mins he cut and welded the work and called me over to check everything was properly seated and sealed. Turned on the car and made sure I had no exhaust leaks and passed smog. 🤷♂️🤷♂️
If you are in CA, only buy a CARB approved cat, or you'll be sorry when your check engine light stays on. The chinesium cats are junk. Don't waste your time amd money.
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 .
If the mounting for the gasket and graphite seal is really that poor then chop the aftermarket one off and weld the oem one to it, I mean there IS a solution, just kinda sounds like complaining. You are in fact showing that these are not just 'plug-n-play' like the ebay and amazon listings would have you believe, so good on ya for showing people that.
Yep, I'm just showing they aren't plug and play like advertised. I had to chop and weld. It worked, but it was not right they advertised it would just "bolt up"
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?
@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.
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!!!
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.
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!!

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
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.
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.
its not entirely from overseas, some parts are sourced from Canada... but the point is they should "bolt-on", but with my experiences this is quite common to have less than desirable, time waster results. And a proper pipe expander is not $30-50 for one that can expand this exhaust pipe, you need one that is hydraulic..... not cheap.. then you need to cut off and weld on a new upper flange to even have the exhaust seal.
Walker makes CARB compliant converters and Magna Flow Rock Auto has then too whats strange is that the Carb compliant CA models are higher prices state EPA and CARB compliant but then state can not ship to Ca WTF is that about
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.
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.
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
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.
That would be nice, if they included something like this. Unfortunately, the ad shows the new part as a slip over with a clamp to "seal it". I've seen many aftermarket cats just work fine. But these cheap ebay/Amazon knock-offs are out of control. Lol
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
Here's my experience with a aftermarket cat. I bought one and it fit beautifully but didn't fix P0420 code. Ended up having to buy Toyota OEM cat to fix code.
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.
Damn I wish I saw this video before I bought one of eBay for my 07 Nissan Sentra. This damn PO420 light is still on even after I replaced my cat. 🤦🏾♂️💀😡
@@subtledriver Hi and thanks for responding. Yes I did and even replaced both o2 sensors. I tried lacquer thinner, Cataclean, guaranteed to pass and I use mid grade gas. I replaced the fuel pump, spark plugs, air filter, oil change, checked fuses, new air intake hose, PCV valve, intake gasket, valve cover gasket, tires, MAF sensor, brakes, rotors, struts, checked for leaks/holes and still the same problem. I just think that my 07 Nissan Sentra 2.0 might be the worst model ever made by them. I looked all over line and I'm not the only one who has/had this prob. I've spent so much money trying to fix this prob and I get horrible gas mileage. I get about 13-15 city and the same hwy. This damn P0420 code just won't go away and it's the only code that I've always had. Other than that the car runs fine. 🤷🏾♂️🤦🏾♂️💀
I realize this comment is a year old but for the sake of others who might see it, fill the car up with non-ethanol gas and drive it for a few days until the codes clear. This has worked for me twice now on two different cars. After the smog check go back to cheap gas. Hella cheaper than a cat...
I bought a set of 3 for my Acadia. Bad decision. They fit, but were much smaller. No directions which was an issue because OEM used studs and the Amazon ones did not. The bolts weren’t strong enough. And, the gaskets were a joke. And, my CEL is back on despite everything running in tip top shape and replacing my 02 sensor. I’m supposed to live with the CEL because they simply don’t work. My recommendation is to read the reviews and notice that they don’t ship to certain states (those with emissions testing). Sucks to need cats and have to shell out so much money, but you’re wasting money on the cheap $100-$150 cats on Amazon. That’s worse.
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!!!
I ordered one for $116 from Top Converters over 4,500 sales and a 96% rating. eBay Guaranteed Fit As part of the eBay Money Back Guarantee, this item is guaranteed to fit your vehicle. It was a lot cheaper. It sealed as it should. After installation I checked for leaks, none found. Codes reset. Some are great deals. I would have returned it for a full refund before modifying it. You definitely had one that was poorly made. I would recommend to never modify one unless they can’t return it. eBay has always stood behind parts I’ve bought for my customers. Catalytic Converter Thiefs should be horse whipped!!!
My experiance on ebay is hit and miss, I've bought from Ebay and everything fit well and sometimes not. This time I tried Amazon and the CAT was about 1" shorter than the OEM.
I got my catalytic converter stolen, people who are inconvenient working people should go to jail with a heavy penalty: they will think twice going under another car.
jeez, bro.... you are a TERRIBLE mechanic if you think these are actually issues. dang bro, this is stuff that is everyday stuff that comes up in working on cars. Dude, JUST DO THE WORK AND ADJUST AS NECESSARY. its not rocket science my dude, just break out a die grinder and make it work, break out a cut off wheel and make the pipe slip into the other pipe. it really is that simple and that straight forward. You are the problem here my friend, not the parts that were ordered.....

There is NOONE worth that There is No Exchange WHATSOEVER worth my/your immortal soul's condemnation Even if G O D H I M S E L F would offer a million years of any/all desires I could imagine BUT after that --> the Lake of Fire FOREVER NO WAY!
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
Ohh man, all this crybaby BS... A real muffler guy would just cut the end that came with is and use the OEM flange, them use the expander to open up the other en and slip it on. A little welding and BAM DONE! LMAO!!
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.
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.
The only thing you should be fixing are sandwiches. How do you do exhaust work and don’t have pipe expanders????? My guy you have the old flange cut the new one off weld the old one on. You are a terrible mechanic you make us look bad.
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 .
Weld the front oem flange and pipe you have onto the new, so weld both, front and back. Way cheaper. Not sure why not. Ive welded many complete exhaust systems. Go to a real exhaust shop.
The problem is you are a ROOKIE mechanic and doesn't know wtf he is doing . Send that customer to my shop and i will happy install it and jerry rig it so it works.
They always have something cheaper that has something little wrong with it well usely something little like this Ive had good Luck nothing serious with anything online can always make it work for 5-20 more with wraps an jb weld and other stuff
So you’re definitely not the exhaust guy to go see then. 😂cuz you have all the tools to weld and cut and your trying get out of installing this part. Shame
suggestions for decreasing theft online included regulation of pick a parts places that buy them. Welding cat on, plate for cat...those dirt bags stole car and left meth pipes in a childs back pack in my car. they like easy... easy to get childrens stuff, and old vehicles cats....
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
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.

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.
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.
How did you hook that up? You should be doing Ytube videos and make bank from going viral….
I would of grinded down that seal to fit the flange or reuse the old seal if I could.when you tighten the whole thing up that seal will conform to any deformities.
Exhaust pipe stretcher???
Yeah, and cut a slit and weld it later
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
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
exactly what i do with almost every aftermarket part i get. merge as much oem to it as possible. but i do get his point; people are paying money for "direct fit" now he has to do extra work. so the client loses money on both buying the part and letting it get installed
So you pay less for "direct fit" and end up paying shop 100-170/hr to make it work.. Yeah, that's it. Might as well just buy an OEM CAT and have a longer lasting CAT. Which is what his point in video is.
@@TheWeirdSide1 hahaha youre so stupid bruh
Did you watch the video? That's precisely what he said he was doing.
LoL don't waste your time with this. Make my job easy and go spend 1500 or more on a factory Cat. A new Gasket will crush the the needed fitment. Also on the tail end, it would be better to weld the factory end on anyways. And personally all this Catalytic Converter bs is just that. Feel good nonsense for people that think they are saving the environment. But everything they buy is wrapped in some form of plastic that they throw away.
You take it to a muffler shop they specialize in modifications and making things work. I ordered mine from ebay, went to the muffler shop I trust I was out within 45 mins he cut and welded the work and called me over to check everything was properly seated and sealed. Turned on the car and made sure I had no exhaust leaks and passed smog. 🤷♂️🤷♂️
If you are in CA, only buy a CARB approved cat, or you'll be sorry when your check engine light stays on. The chinesium cats are junk. Don't waste your time amd money.
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 .
Is a Dam shame we don’t have honest people anymore
People stole my friends brand new Dodge Ram Pick up’s Cat. Car was less than a week old.
At least it was under warranty.
If the mounting for the gasket and graphite seal is really that poor then chop the aftermarket one off and weld the oem one to it, I mean there IS a solution, just kinda sounds like complaining. You are in fact showing that these are not just 'plug-n-play' like the ebay and amazon listings would have you believe, so good on ya for showing people that.
Yep, I'm just showing they aren't plug and play like advertised. I had to chop and weld. It worked, but it was not right they advertised it would just "bolt up"
All I heard was excuses, this would be an easy fix.
Tail Pipe expander for the rear, and clamp down the front, gasket will form to fit
I never bolt! Weld it all together!
unfortunately the common man has to bolt stuff up. its not realistic for most people. but i agree with you dude!
I take a Magnaflow converter would be of much better quality, they are pricey though.
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?
It's just a coincidence. The cat controls nothing but a check engine light.
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.
@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.
@Randall Glatt no problem
Don't charge too much for 'em and thieves will stop stealing 'em.
They cost a lot to make unfortunately. And cali laws prohibit lower quality units.
Obviously you have no clue as to how vehicles work
muffler shops have tubing expanders they can use
Question - are there 2 catalytic converters on that pipe.??? Why are there two.???
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!!!
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.
The Amazon one is the one that actually works without welding. Your title is misleading.
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!!
My alarm didn't go off when mine was stolen. Most won't.
@@elizabethfree5294 Im sorry but that's not an excuse to not install a good alarm. Or why someone takes your property..that must have been a sorry sorry sorry alarm..if you have an alarm you should know what its worth just by everyday use and accidentally bumping into the car. Maybe that's your excuse but people should be responsible in protecting their property the best way possible within their means..js
@@ericbaker9688 It's 2021...that's why alarms don't work any better than slapped-together aftermarket, bolt-up wannabe cats.
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
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.
This is supposed to be a plug and play cat, the front flange wont seal, and the rear pipe needs special tools.
@@subtledriver Your correct subtledriver :)
There's always a reason why its cheaper, great video thank you.
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.
its not entirely from overseas, some parts are sourced from Canada... but the point is they should "bolt-on", but with my experiences this is quite common to have less than desirable, time waster results. And a proper pipe expander is not $30-50 for one that can expand this exhaust pipe, you need one that is hydraulic..... not cheap.. then you need to cut off and weld on a new upper flange to even have the exhaust seal.
If your vehicle is registered and smogged in California you need to buy a C.A.R.B Compliant CAT.
Yet another reason to leave California.
Must be OEM. No aftermarket Cat is certified by CARB.
Walker makes CARB compliant converters and Magna Flow Rock Auto has then too whats strange is that the Carb compliant CA models are higher prices state EPA and CARB compliant but then state can not ship to Ca WTF is that about
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.
Is walker a good brand for a catalytic converter
from what I heard yes
Wish I seen this before I did buy mine
Thank you
Cut the tip off the new one and weld the old one on..
defeats the purpose of "bolt-on". BTW I did just that.
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.
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
a better honest video would just explain what i did, and not make excuses about it being hard to install, which it is not.
Ssssssss
Kit I bought front end fits perfectly 👍
Hey regis im going to replace for a friend who had hers stolen. Do you mind sharing your link to the one that fit perfectly? Thank you and HNY!
@@kevinbaker2470 No link. He lied
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.
That would be nice, if they included something like this. Unfortunately, the ad shows the new part as a slip over with a clamp to "seal it". I've seen many aftermarket cats just work fine. But these cheap ebay/Amazon knock-offs are out of control. Lol
@@subtledriver size may be wrong but I attached a link to what I'm talking about!
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
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.
Great Man,, thank you for your kindness words. We need more mechanic like you 🙏🙏
What about the direct fit cat converters
Here's my experience with a aftermarket cat. I bought one and it fit beautifully but didn't fix P0420 code. Ended up having to buy Toyota OEM cat to fix code.
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.
What's rtv I have same problem I just bought mine of Ebay and got check engine light
Permatex Rtv high temp gasket maker
@@bri9435 dude thank you 4 getting back I'm gonna try it out I was about give my car to junker and carry another loan.
@@ghasanahmed6159 no problem. Just make sure you read the instructions, you have to let it set for a few hours. Maybe even overnight.
@@ghasanahmed6159 did it work????
Cheap aftermarket converters are good for seeing P0420/0430 codes and nothing else. Cheap is cheap because it doesn't work and it's crap.
You already have the solution! Just need a little work. It will work.
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.
Out of curiosity did you ever get the ebay parts for your ls swap? How well did it perform?
@@budthechud3408 sorry I didn't. I decided to leave the cats off
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.
It’s CALLED DIRECT FIT …. Get the proper Cat to fit you car and get OEM 02 sensor
Damn I wish I saw this video before I bought one of eBay for my 07 Nissan Sentra. This damn PO420 light is still on even after I replaced my cat. 🤦🏾♂️💀😡
Did you reset the code? What product did you buy?
@@subtledriver Hi and thanks for responding. Yes I did and even replaced both o2 sensors. I tried lacquer thinner, Cataclean, guaranteed to pass and I use mid grade gas. I replaced the fuel pump, spark plugs, air filter, oil change, checked fuses, new air intake hose, PCV valve, intake gasket, valve cover gasket, tires, MAF sensor, brakes, rotors, struts, checked for leaks/holes and still the same problem. I just think that my 07 Nissan Sentra 2.0 might be the worst model ever made by them. I looked all over line and I'm not the only one who has/had this prob. I've spent so much money trying to fix this prob and I get horrible gas mileage. I get about 13-15 city and the same hwy. This damn P0420 code just won't go away and it's the only code that I've always had. Other than that the car runs fine. 🤷🏾♂️🤦🏾♂️💀
I realize this comment is a year old but for the sake of others who might see it, fill the car up with non-ethanol gas and drive it for a few days until the codes clear. This has worked for me twice now on two different cars. After the smog check go back to cheap gas. Hella cheaper than a cat...
I just bought a car from an auction and the car was transported to me with out catalytic converter.
That's BS
I bought a set of 3 for my Acadia. Bad decision. They fit, but were much smaller. No directions which was an issue because OEM used studs and the Amazon ones did not. The bolts weren’t strong enough. And, the gaskets were a joke. And, my CEL is back on despite everything running in tip top shape and replacing my 02 sensor. I’m supposed to live with the CEL because they simply don’t work. My recommendation is to read the reviews and notice that they don’t ship to certain states (those with emissions testing). Sucks to need cats and have to shell out so much money, but you’re wasting money on the cheap $100-$150 cats on Amazon. That’s worse.
See get to work sizing a pipe and just weld both ends. Duh..huh...Or you could spend 2k on an OEM converter.
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.
How much louder is straight pipe ?
This mechanics thinks that all the jobs are easy money and always complain of different parts just make it work weld it or mod it that's all
Thanks for sharing. My mechanic has pipe expanders , welders, grinders and skills to make it work. That’s because he has years of experience.
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!!!
I ordered one for $116 from Top Converters over 4,500 sales and a 96% rating. eBay Guaranteed Fit
As part of the eBay Money Back Guarantee, this item is guaranteed to fit your vehicle.
It was a lot cheaper. It sealed as it should. After installation I checked for leaks, none found. Codes reset. Some are great deals. I would have returned it for a full refund before modifying it. You definitely had one that was poorly made. I would recommend to never modify one unless they can’t return it. eBay has always stood behind parts I’ve bought for my customers. Catalytic Converter Thiefs should be horse whipped!!!
My experiance on ebay is hit and miss, I've bought from Ebay and everything fit well and sometimes not. This time I tried Amazon and the CAT was about 1" shorter than the OEM.
I got my catalytic converter stolen, people who are inconvenient working people should go to jail with a heavy penalty: they will think twice going under another car.
jeez, bro.... you are a TERRIBLE mechanic if you think these are actually issues. dang bro, this is stuff that is everyday stuff that comes up in working on cars. Dude, JUST DO THE WORK AND ADJUST AS NECESSARY. its not rocket science my dude, just break out a die grinder and make it work, break out a cut off wheel and make the pipe slip into the other pipe. it really is that simple and that straight forward. You are the problem here my friend, not the parts that were ordered.....
So:
All thieves have their part in The Lake of Fire
Which includes eternity of existence burning in molten lava
NOT where anyone wants to be.
There is NOTHING
in the entire universe
Worth being condemned to that fate.
There is NOONE worth that
There is No Exchange WHATSOEVER
worth my/your immortal soul's condemnation
Even if G O D
H I M S E L F would offer a million years of any/all desires I could imagine BUT after that --> the Lake of Fire
FOREVER
NO WAY!
Just use a lil exhaust putty to seal it. That is what I would have done.... Imma make it work!!
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
Ohh man, all this crybaby BS... A real muffler guy would just cut the end that came with is and use the OEM flange, them use the expander to open up the other en and slip it on. A little welding and BAM DONE! LMAO!!
I bought some for my 2006 Toyota tundra 4.7. And my check engine keeps coming on. 😢
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.
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
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.
The only thing you should be fixing are sandwiches.
How do you do exhaust work and don’t have pipe expanders?????
My guy you have the old flange cut the new one off weld the old one on.
You are a terrible mechanic you make us look bad.
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
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 .
Weld the front oem flange and pipe you have onto the new, so weld both, front and back. Way cheaper. Not sure why not. Ive welded many complete exhaust systems. Go to a real exhaust shop.
Mine worked just fine, Just cut it , weld it, works like a charm, Charge em alil more for the time involved & stop crying
Update ebay...the ones from Canada great quality better than factory welds
Which vendor is that??? most cheapo ebay ones look like crap
Premierautoexhaust
This gaskets soft and take shape
yes, but original gasket is designed to pivot and seal with spring tension, crush seal will crack the manifold.
A Prius I didn’t know toasters had catalytic converters
The problem is you are a ROOKIE mechanic and doesn't know wtf he is doing . Send that customer to my shop and i will happy install it and jerry rig it so it works.
my cats with o2 sensor was cut off of my 2000 ford crown victoria police interceptor before i bought it now what?
They always have something cheaper that has something little wrong with it well usely something little like this Ive had good Luck nothing serious with anything online can always make it work for 5-20 more with wraps an jb weld and other stuff
So you’re definitely not the exhaust guy to go see then. 😂cuz you have all the tools to weld and cut and your trying get out of installing this part. Shame
Getting an oem cat in california is about 4k maybe you should work for the dealer,they like this kind of problem solver people.
Any exaust shop can easly fix that. You sound like a rookie. Better to buy aftermarket than to comply with the dealer prices of a cat.
suggestions for decreasing theft online included regulation of pick a parts places that buy them. Welding cat on, plate for cat...those dirt bags stole car and left meth pipes in a childs back pack in my car. they like easy... easy to get childrens stuff, and old vehicles cats....
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
I just waited 7 minutes of my life watching this that I'll never get back. Two easy fix's. No need to make a video of this. What a waste of time
