This video is going to be popular amongst the tree huggers . You guys are completely missing the point of this video. My sister lives hours away. Option 1 was to do nothing and she drives home with a car that sometimes won't go over 35mph , try merging on an express way like that , it could also damage the engine because at full throttle I could hear timing chain rattle.....option 2 I hollow out the convertor and she can drive it safely and not destroy her engine. Of course the convertor should get replaced, this was a "bandaid fix" , no different from putting a plug in your tire in a pinch and later taking it to get the tire repaired properly or replaced.

This is the mechanic YOU want working on your car.. over FaceTime he was able to get me going and off the interstate. Thank you for taking care of sharky "turd” wouldn’t take it anywhere else.

For two months, I have been watching car repair videos to solve the problem of my car, which is the same as in the video I have not seen a similar video, any magnificence and creativity, thank you from the bottom of my heart

Great repair video! Very detailed ! Thx for sharing info on how to fix the problem.

My car is doing the same thing, when I'm parked and I accelerate it only goes to 4 rpms. Thank you so much for making this video. You have saved me time and money.

Perfect diagnosis. I say job well done.

Great diagnosis and perfect treatment. Thumbs up, well done,

🤣..Mike calls everyone's car a turd..even his sister's car..love your videos..I learn a lot!

I just went through this exact problem. And my mechanic came to the same conclusion with the same repair since my state doesn't require emissions testing. Restored the power and driveability as years before.

Great 👌 job. Like the way how you find the problem and fix it.

No check engine light on the dash!!!! Waow! Great work 🐥🏖️👍. Thank you for sharing.

Thank you for the video, Mech a nic!

Excellent video thank you for your help.

Wonderful! Excellent! Well done

Thanks so much for this video!!!

sometimes we watch these videos to brainstorm our own problems, once you said rattle it sparked a memory of what the heck is that noise, so I am replacing the cats on my 2008 dodge charger, she's got lack of power especially after a highway trip or it idles or its over 79 degrees out. Everything is new, from block out. She has a problem at first start with a up and down idle and sputter then evens out until it goes open loop. I finally got a code that went away but it was b2s2 stuck in rich, that could be a different issue or related to the cats. I have hp tuners for the car and ever since the update I can't see my o2 sensors anymore, but I run learning (off) peddle adaption (off) and I have it getting its values from the map.

Thank you sir👍

Great job,

You gotta do what you gotta do. I get it man. I'd do the same for family.

Good job sharing

Good job

thank you

So, technically speaking, you could get it smogged with the OEM cat, as it is? Then put on a non-OEM cat. Makes it registerable and Sellable

Great video. The catalytic converter was blocked. But with the temperature check it looks good. Why is that? Thanks

I wonder what the exhaust readings are now that you did this ...how much more had it caused the vehicle to raise its emissions....if at all lol

Its only temporary if it doesnt work right? I would just stick the "test pipe/bung" on it and be done with it. Then she will not get the P420 code showing up. Although I know some cars depend on the downstream sensor to adjust fuel trims or what ever. Evidently that one doesnt. Bought my moms 2006 Buick Lucerne and the cat was failing. I just "adjusted" the O2 downstream sensor and everything is fine. Its not plugged though.

Couldn't you clean it/wash it with lacquer/thinner? And/or a non corrosive cleaner? and leave it overnight? especially if she's on vacation, which means she won't need it for a few days. When you mentioned "Hollowing" out the cat, I chuckled because that's what Turbo Audi people do.. Plus using an o2 sensor spacer/bung...EDIT: Never mind.. It looks like you fixed it.. Glad she saved a ton of money in the process.. Now she needs to pay you, with a nice WARM meal.. LOL!!!

thank you for the video i have toyota yaris cross when i try to go uphill the mountain it seems like car has 5 horsepower and rpm has a problem also go up especially when there are 4 people car moves like a turtle makes too loud sound car goes normal on the road but sometimes has problem acceleration also seems like not accelerate much sometimes my car has a weird sound i mean it feels like mustang exhaust sorry for the english sir what can be the problem i live in turkey i took toyota they said it is normal .here dealerships dont know anything

Nice one Johnathan 👍

Great video... 2017 Hyundai Tucson... 77350 miles... Same symptoms... I'll comment in a few days if it works....

Have same issue with my 2016 Tucson. My mechanic need to check further but he guessed it's a blocked cat. Hyundai here in canada quoted me CAD$3300 just for the CAT and a few hours labor plus tax to replace. Probably $4000 all in for this issue - crazy!

Interesting video. Thank you. I am wondering if you simply removed the 1st O2 sensor, would there be enough escape of exhaust to notice an improvement of power? Of course the engine would fault to open loop (no O2 sensor to regulate the mixture) and will trigger a fault code. I'm not suggesting it as a fix, just as a quick easy test before replacing (or gutting) the cat. Your test for blocked resonator/muffler was good, but as you guessed it was the cat. I don't think I've ever experienced a blocked muffler... but I guess mice can do anything, anywhere.

Old video but good video 2020 elantra limited. Exhaust manifold getting red hot. Car drives great! No bogging. No hesitation. But when driving hard for a bit, boy does it glow. Would you say thats the cat on the manifold that is clogged. I hove no codes or cehck engine light

I normally am entertained and amused, but I have reservations about hollowing out a catalytic converter. Loved the episode though.

They usually get blocked by excessive oil consumption. Was it using oil?

If it works it works. What sux is a 2018 with failed cats. Out of warrenty for hyundai?

Bro can you help me my car is mutushbiiz Rvr can not speed up low power can you help me

Could putting an aftermarket O2 sensor cause the same symptoms? I feel that after I replace my cat and my upstream and downstream O2 sensors I have the same issue, or should I look somewhere else first?

My car have acceleration problem and some time missfire but no check light. Mechanic is only resting ignition changed the coils but issue not resolved. Please guide

There should be some backpressure it really depends on the vehicle (turbo charger and even the amount of cats type of exhaust will effect it) most manufacturers will provide a specific range of backpressure but a general rule of thumb is anything over 8-9psi is too much (for a NA engine)

Is hollowing out the part ok in the long run ? Or is it recommended that I get a new one?

Dude, you just did your first cat delete that's good for another 50 Hp on that Tucson, funny how you even call your sister's car a turd. I get it now any car that is broken is a turd and some are more turdy than others. Lmao, Good job brother!

Excellent fix. I'm facing the same issue. hyundai close to Vancouver want $3300 just for the CAT, plus labor (and taxes on top) - mine is a 2016 so spending $4k seems like a lot right now. One question if you have time to answer? Did any warning lights come on afterwards (due to oxygen sensor that's present)

Let me think about this for a second….ok I’m done, I choose family over tree huggers any day!!!! Great video bro!!!!

How sudden did this loss of power symptom happen?

This was my first thought on my wifes 2016 tuscon. Thise engines consume oil and clog the cat. My only concern when i break that shit out is how much louder it will be

Did the check engine light ever come on after or any codes?

I have a similar issue with my Mazda 6, but I still can’t figure it out I’m gonna try to remove the cat to see how it drive

Must be nice to have nuts of exhaust come off like that

Could have done that check thru the booster hose intake side.

Ong. I have a 2018 Hyundai Tucson!! My car goes 25 mph. My air filter is new. It is new since Jan 2024. I should chrck for a mouse nest?

Did the ticking stop?

Why not use a chemical, like a c.l.r. or something to break up the garbage inside without hurting the platinum?

I have a 2013 Kia Optima that powers down after driving 30 minutes or more - and when I get out I can hear the exhaust system crackling with heat 🔥from underneath.

I hope the EPA isn't going to get on you about messing with the converter on that car even if it doesn't have to go through any testing.

I just had my catalytic converter replaced… bent valves replaced, i don’t understand why it’s still restricted

Does removing the catalytic converter bad for your car?

My Np200 has no acceleration power ..the rev mught be high but it moves at 40 km perhour..

Most cars have more than one catalytic converter. How do we know which one is bad?

I replaced the air filter, the MAP sensor. It didn't fix the issue, I took it to the mechanic and he said there was no power, and he didn't know what to do because there was no code.

Remember folks ; the 100th comment will receive the catalytic converter contents !

Location

No check light there how

Bit of advice: 1) With the cost of cats right now, you should have cut it off and sold it. The rare materials are still recyclable and valuable. Not to mention the health hazards that come with drilling out the material. 2) I am very surprised you did not trick the downstream O2 sensor with a resistor & transistor. You'll have very rich combustion if the downstream O2 reads high after the cat delete.

Dam rigging a nice car !! I would not use you to repair my car!!!

Take to the motorway and push it badly on 3 4 th gear all the shit will go out belive me people use to give me blocked exhaust cars 😂😂😂 when i done oil change go around max out all the shit flys out 😅😅

My kia soul is doing the same thing

Any Codes Tho?

Damm Why No Check Engine Light?

Why didn’t you simply washed the cat?

Just recently been studying abiut cars for diy. I come to find our something like emmission seems to just be some woke crap haha

FIRST

Your vids hv not been coming up in recommended 😡

dude the car needs to have some back pressure if u disconnect the muffler its gonna lose power completely

Don’t agree with removing the catalytic converter .! Bad fumes smell and not good for your sister. And more pollution, not a tree hugger but it’s not good!!

You know how girls are they live everything for tomorrow.....no buddy knows what tomorrow they talking about....
