- This video will show you how to fix a seemingly fine catalytic converters (FOR OFF-ROAD ENVIRONMENTS ONLY) so that your check engine light turns off. The benefit to this is allowing the check engine light to come in and notify you of problems instead of thinking your engine is fine. If you have a light on a performance OFFROAD ONLY vehicle for this, then you won’t know when your engine throws other codes.

The straight ones that are really just sparkplug defilers that you drill out to fit your O2 sensor do work and very well I may add.
Tried the straight before Dan, no joy. Never even knew these existed, thank you so much brother!! Have a great thanksgiving!
I’m glad you saw the video and glad it will help! Happy Thanksgiving! Enjoy it!
I love it, you just saved my day,my wife wants drive a vehicle with the check engine light on and it just threw it on due to catalytic converter and it still runs great with plenty of power! Will be ordering a 90° spacer tomorrow
How’d it go?
did it pass ? they do a visual insp on o2 sensors ???
If you find a link to buy please post it here! Thanks
😂 Straight, 45 and 90, some $10-20 stainless or iron steel
Spark plug anti fouler and a 1/2” drill bit work as well. They’re at all major auto parts stores on the shelf.
Did it, used dish soap abd itvworked, thanx a bunch ! 🤗
You can correct for that and also a tired O2 sensor with a potentiometer to vary the signal voltage. Mechanics have and exhaust gas analyzer to make sure you got it right. Also, if your cat is tired, you can remove the spark lead (safely) to one cyclinder and the unburned fuel will make the cat go red or even yellow hot. Red is enough - about 5-10 minutes. But have a fire extinguisher handly. It cleans up the cat without any expensive chemicals. On a gasoline engine.
That’s a big tip!
Where is the spark lead do u have a video doing it ?
I used the straight double stack parts store defouler method on my 98 chevy. Worked great. Drill one out for the o2 then stack it on the unmodified one with the small orfice on the end, then screw the assembly in the exhaust
Exactly what I did, 09 Dodge Journey
This worked on several of mine.
Answered all of the questions I had. Thanks a bunch.
Hope it helps!
Very well said. Thank you sir.
I just used 2 spark plug anti-fouling extenders and it worked great
Did you jack your car up to do that
But didn't you have to drill hole bigger
@@reginaldlarry2962 i did for 1 of them
Great awesome video bro ! Obey all law's 🤣🤣🤣 I just had to subscribe 🤣🤣🤣
The front sensor is for monitoring air /fuel ratio and controls fuel management
Yup. The computer also takes that info for emissions. But it also does that. 100%
Really enjoyed the tip.
What a great explanation! You just got yourself a like and sub!
Thanks for the tip!
Hey I did this on my car, it worked!!! Of course I only use my car off road😉
Bingo.
Where did you buy it?
Can you post a link to where you got those extenders do you think a person could possibly make one themselves
nice going you gave it to me strate keep up the good work
Appreciate the support.
Thanks for your tips
IT WORKED!!!! It friggin worked!!!! I had to go back and find your video and tell you thank you this SH%* worked🎉🎉🎉 Dont forget the blow out part but baby it WORKED❤❤❤
Woohoo!
Where did you buy the extender from?
@randallwillis8286 I heard walmart sales them
What is the blow out part? Just debris? Let it run a bit before adding the sensor? Where did you order it and was it just plug and play?
Where. Did you get the? Spacer from
My man thx for the info. Mechanic wants $1630 for catalytic converter and $250 for labor. Jeep is 2012 unlimited sport wrangler with 100,354 miles.
Kind of nuts. This doesn’t always work on every vehicle…but hopefully it does for you. They got super smart with the tubing on more recent vehicles and it won’t throw a cat code but it will throw a “slow to respond code”. Meaning the time it takes the second sensor to respond like the first one on deceleration is too long. They are trying hard to eliminate the work arounds. But on lots of vehicles this works.
@@WarPaintOffroad ❤❤❤❤😊¹😊ààa
Glad I saw this 😄 Firestone tried to take me for a $2159 ride that was O2 sensors included. I knew something was fishy when they charged 200 apiece for those plus $100 labor bringing them to $500. I can put those on myself. Hell if it's bolt on/ screw on I will give it a shot.
@@sarahshear5132❤
Change the coolant temp sensor to avoid losing half the new cats lifespan in 800 miles.. not troubled in 30yrs?? New car 30 years pollution at buy! 600$ commission on cat sale?
I'm here, for the catalytic converter info, and didn't realize you did the 4X4 upgrades etc. I do have a Ford F150 4X4, but it sees little use in the back country these days. It's still all OEM, and I've always owned an ATV for back country jaunts, to myself living here in the Pacific Northwest of Canada, but have travelled to Utah to the many off-road locations, and have seen some awesome scenery in doing so obviously.
Fantastic! Super cool.
I have done the spark plug spacer for an o2 sensor 3 times and every time it worked lol so I’m moving to the next video lol
You have touched on literally every issue I’ve ever had on my jku 😂
Hah. That’s too funny! Just trying to pay it forward and keep the channel growing!
It's because it's the few issues jks get.
@@callmesomething1425 some are certainly more common than others. But this isn’t a jk issues. This is on every vehicle made with cats. We just lucky that some of us use Jeeps offroad only making it okay to do this.
My trailblazer 2005 says that about unefficient cat. But runs good. No cloggage. I guess I need to work on the last sensor
Mine is p420 I bought a 2004 Honda accord ex sedan the cat was stolen they had a universal one on there I bought one for 170 and replaced the whole exhaust and the engine light came back on after a month
I'm trying the straight one but I put two tougher see what happens if it doesn't work I will change to this one, thank you great video.
I don’t it just depends on the vehicle and the condition of the cat. Sometimes they’ll work, sometimes they won’t. If the cat is clogged enough…it won’t matter.
Did the straight ones work?
Here for it! CRC emissions cleaner. It says pour in when @ 1/2 tank but just filled up. Hoping it fixes my issue. 🙏
Results?
I did it the CRC and don't work
Definitely a great modification to fix emissions on any off-road rig!
Thanks Brett!
Remove bank 1 sensor. Spray carb cleaner into hole and sensor. Replace. Rev engine. Repeat.
Lacquer thinner will work as a cleaner. Clean clean clean. Mass air flow , bank 1 and 2 sensors , catalytic converter.
Catalytic converter has a weird looking screen that gets clogged. If screens damaged no spacers or cleaners are gonna work
For sure!
Good job
Thank you
Can this help with getting the catalytic monitor to turn on?
Thanks for explaining how they work. I had been trying to google that, and been trying to find the explaination. Makes sense why the elbow version works better now.
Thanks again
Hi good afternoon. Got a question I have a nissan altima 2008 2.5 and it gave me cod P0240 . When I put the car on drive it makes a loud noise and it go on reverse when it on drive. What that me is it my axle is broke.
Fantastic explanation plain and simple 👏
So with this your cat plugs up an you don't know it?
This guy should be an engineer at dodge ❤😂 ,
What do you think about those rislone , cataclean ....etc products ?
Nice video 👍👍
How you doing sir I was wondering if you can tell me where I can buy that extension the one you were saying the
Thank you for this video I really do appreciate it. Is that copper o-ring that comes with the j-spacer supposed to go on before you screw on the oxygen sensor basically between the spacer and the oxygen sensor?
The o2 sensor has its own o ring.
@@WarPaintOffroad got it Thanks for your response. Thanks for the video
Can it be removed and plugg the hole?
Thanks
Good info!
Thanks for the support!
Where can we get that from?
Best video. Thanks.
My car has one oxygen sensor. No downstream sensor. No cat. The cel is on. Will it work?
i replaced both sensors and after i replaced them this codes came on🙄 my car is running good
Am a new subscriber on this channel
Thanks for the support!
You said ALL cars have 2 O2 sensors well mine doesnt it has 1 on a 86 ford ranger 2.9 L v6
On Nissan, if you drill out the tip of an anti-fouler plug so the rear 02 sensor will be pulled out of the main exhaust, it tricks the pcm into believing the cat is working
Interesting.
Did you use 2 or one non foulers?
Would you recommend for an 04 suburban? 😅
it doesn't read less exhaust it stabilize the voltage signal sent back to the ECM and in actually the distance it spaces is more important than straight vs 90 if room permits you can use 2 straight spacers to get the same distance as that 90
Depends on the vehicle. Some are now programs to see the change within a certain time limit on deceleration. So Spacing it too far would still cause a light.
Where did you order that 90 degree defouler from? I've looked everywhere for one and can only find the straight ones which won't fit into the small space that I have.

Great video. is bank 1 the sensor top side of the cat🤔
Bank one is the rear or right side
Where do I get that from
What part is,it?
Where do you get that curved spacer?
Need some advice. I have a 96 ford four winds class c motorhome. The cat was stolen. The RV ran rough when i bought it 3 yrs ago. No engine lights on. Now i need to replace it. I hardly drive it. Can i just put a straight pipe on it ? I dont know if the o2 sensors were stolen also. It is expensive to replace and the muffler shop wants to replace with after matket parts. That does not seem fair. The ins co needs to compensatee for one of like kind. I know RV is old but I need some advice. Cop told me off record to just use straight pipe. Im 56 yr old female with very little knowledge or help on this matter. Any advice would be appreciated. Thanks.
I would replace the cat with an aftermarket one. It will still be cheaper than replacing it with a factory one and will still do what it’s meant to do. Because it is an on road vehicle…I would replace it and be sure to follow the law. Fines are really big if you get caught. It’s just not worth it.
What's the part called
Cant find these anywhere, please help!
what should i google to order this
Is it just mandatory to replace the catalytic converter once the P0420/6 shows up or replacing only the sensors can get it fixed?
Depends. Honestly it could be an exhaust leak causing the code too. So it’s easier to try and replace things that are a bit cheaper first.
It's interesting I got a 2008 dakota with a leaking exhaust manifold and no one makes new one the all warp I'm told this just happend to get a p0420
Yes. An exhaust leak can cause this code too. It’s still a cat code… it an exhaust leak can affect the readings. It’s very possible.
Have an off road vehicle only & while the light doesn’t illuminate, it still shows up when scanning ( bank 1 ) P0420 code. Any tips ?
That’s strange. It could just be that the computer has seen the issue, but hasn’t seen it often enough to throw the light. A computer usually has to see it 3 times within a certain amount of runtime/mileage for it to actually trigger a light.
Ok Thx , can you do a video on actually installing the hack on a 2014 jeep wrangler with two cats
thats part needs to be install in the 2 o2 sensor? The one after the cat?
Usually the one after the cat.
Whats your advice for me: i am from kirdistan of iraq. Our fuel is very low quality. I have jeep cherokee 2.4. It always shows the code p0430, and engine light on.i apreciate your advice
Move away😂
It's not looking for dirty air it's looking for oxygen. In reality your J pipe creates a venturi effect as the exhaust gases pass by the opening so the sensor will never see anything as the tube will have a vacuum in it. Good idea I just don't think you have a full understanding of how and why it works. Thanks for making this video.
Bingo
What if there is no light on dashboard but when scan obd getting the code P0420:00-64 Catalyst System
Efficiency Less Than Threshold
Bank #1
If i add this spacers for o2 sensor, its just for clear the error?
I’m dealing with the same thing let me know when you get a reply
Great info thanks!
Where do I find the part.
You can find them with a google search. Sometimes on amazon or eBay.
Hell yeah I've got an 89, year 1, 5.9 cummins ram you can go to town on
I have a Subaru STI, 2019 and got a P0420 code. I bought a new O2 sensor and new cat, the code still comes back. COBB is saying I need to install an OEM downpipes from the turbo. I have an upgraded high flow downpipe. Grrrrr....
I’m. It a Subaru expert. But I have had other vehicles that have performance down pipes off the turbos. Sometimes those high flow cars aren’t enough to meet the standards. They were in the vehicle that I had…but I have heard of that happening too. I definitely wouldn’t mess around with it if it’s a street driven vehicle. Lose some power, meet the emissions standards. Be in the correct side of the law. It’s just easier and the right thing to do.
Yesss.yess..offroad 😉
Lol the neighbor we hate to breathe..classic
😂
Can anybody tell me where do I get it from
Which should it be installed on first or second sensor upstream or downstream?
The second.
@@WarPaintOffroad Thanks
What size should be used or is there a standard size?
Hey love your video my car runs fine but have sometimes has dead spot on acceleration i do smell a strong exhaust smell start up and while idling i think my catalytic converters are starting to fail what do u think
I have the exact same problem taking mine in this week
It could definitely be a cat failing. When the honey comb inside the cat gets blocked or corroded enough…it can fall apart and block exhaust flow. It very well could be that.
Thanks for replying 👍
This is not the cat. This is a failing “fuel pressure regulator”. Look that up for specifics for the one on your vehicle.
What if I just unscrew the 02 sensor and tape it off somewhere
That wouldn’t work. Because the sensor needs to read something and it knows what it’s looking for. If you pulled it out and taped it off it would absolutely cause a check engine light…
where can I get one ??
Laquer thinner hack works also...
???
My truck has two cats on the downpipe. The sensors are both before the 2nd cat. Can I remove that 2nd cat without getting a CEL? Seems like you should be able too since the 2nd cat is after both sensors. Any advice would be greatly appreciated!
If you don't have a sensor after the second one, then yes you can remove it. It's probably just a resonator and not a cat
I’m new to the channel just wanted to say hi
Thanks for the support!
I have a 2012 dodge Durango with this work from my SUV?
It might. It just depends unfortunately. Depends on how worn out everything is.
I want to do this except I want to HOLLOW the cat AND install this with 2 straight extensions AND one 90.
On my “off-road” Lexus sedan of course. 😅
This only works if the cat is mostly ok and functional, just “weak” and not making threshold values.
Your hallowing would be a cat delete which will require programming the cat out of the fuel tuning loop.
Ford should be sued for making it so expensive to have to change exhaust manifold with cat. Maybe others do it too but ford is the one i ran into.
Yea they do that to force people to go back to the dealer. At least that is my thinking. The Mopar Pentastar 3.6 molded the exhaust manifold into the cylinder head. To you just bolt up the cat to the head and then to the rest of the exhaust. It’s fairly simple. But it’s. Ot quick enough or accessible for the guy with a saw that wants to steal it. So you never heard of the 3.6 Mopar having its cats stolen. Kind of cool.
All the dealers should be sued they sell us there problems for way too much and once a problem is discovered they just tell you what the repair is and if you have their warranty they try not to honor it
Nissan as well
Yes my Lincoln MKX has engine light on and says it the Catalytic Converter
So where do you get one of these extensions?I need one
Hey where can I buy it ?
I can tig weld really good im a try this ill keep you posted my Subaru cat is a dealer only item. 2K ouch
Crazy right?
The biggest hack for this issue is not this one. The best hack is to vacuum seal the downstream O2 sensor, and plug the Cat Conv hole. This way, the O2 sensor due to vacuum seal will not sense any O2.
That’s a great tip. But…it won’t work on new-ish vehicles because the second sensor needs to see a change in less than a quarter of a second following the other O2 sensor on deceleration. They programmed that in to ensure people don’t do what I mentioned or what you mentioned. But you can play with the distance on the extension to make it happy. So it just depends.
do you have a link for that J pipe spacer by chance?
I don’t. There are so many companies that make them. Just google it and it will pop right up.
Where do you purchase this product or the two piece unit mentioned?

I just bought a 2010 Accord ex-l 2.4. During the test drive there was no check engine lights, of course Now there is, the owner stated it had the same gas in the tank for perhaps 6 months, could old/bad gas cause p0420?
Bad gas can cause all sorts of things. Start with fresh gas and a fuel system cleaner to be sure.
Thanks, Starting with the Lucus high mileage.@@WarPaintOffroad
Four minutes in, and I realize this won’t work for me. I live in a state that does not require an omissions check. So when my converter was stolen, I paid a man $60 to weld on a piece of pipe in its place. I was told there are ways around P0420.
Po 420 is the coed I just got one on my truck to
I'd love for you to look at my car ...I love learning so I'm not stranded..
Ok I have a question , I have a 2017 GMC Sierra and the light come on and it seems to be running fine . Code says it’s the cat on the right side. I noticed my fuel mileage has dropped but it still runs good other than a drop in fuel mileage. If I put one of those on will it cause the light to go out and will my fuel might come back ?
What other codes is it throwing? I have a 2014 Sierra and am facing similar issues. I had 6 codes, down to 2, P0171 and P0430 - likely have a vacuum leak somewhere. I don't think a bad cat is the reason for your mad mileage, but something else is causing to mess with your fuel air ratios that messing with your O2 sensors.
clean your MAF sensor
I got the same code po420 but whenever I drive 45-1 hour on the highway check engine goes away for 1-2 days then come back on again
Maybe is not clogged completly. Use cataclean cleaner
Will this still work if your cats are gutted out? I'm thinking about having mines gutted, so they are still there visually!
cool off-road only trick.. btw does anyone know which do calld cat cleaner, if any, actually cleans the cat.. I’m looking at cataclean & Rislone, but getting vague descriptions on that partiqular topic ironically 👋😑
Same. About to just take it off and let it soak in the bathtub with degreaser lol
Cataclean didn't work for me and I can't get my $29 back from Napa Auto Parts. Try Seafoam instead.
My 2023 F150 powerboost check engine light came on and when I checked the code it was P0430 code I noticed immediately my gas mileage improved by 10 MPG on the highway then I cleared the code and the check engine light went away and I lost the great MPG, however after driving my truck about 400 more miles b the check engine light came back on and the code reappeared and I once again got 10 more MPG on the freeway. I also noticed that when that error code appears it uses the electric motor more in low speeds than what it does when the check engine light is off. I’m happy with not fixing the O2 sensor since I get 10 more MPG can anyone tell me what is going on?
I’m not exactly sure other than to say it’s in the vehicle’s programming to run the way it does. It using the electric motor more might be your gain in MPG. It could also just be the way you happen to be driving it…slightly less traffic, slightly flatter routes can make a big difference. 10mpg is a lot though. So I would think it has to do with the tuning and the electric motor running more often.
For a P0420 code, do you extend the sensor on the passenger or driver side?
That code refers to bank 1. Bank 1 is whichever side of the motor has cylinder number 1, so it would depend on what motor you have in your vehicle. At the same time, both Cats have exhaust flowing through them at the same rate. So if you have it for one side…the other side probably isn’t too far behind and will probably throw a code soon. Just remember though, this is for Offroad use only. If you are doing this in the street to cheat emissions….you are risking a big ticket and fines of caught. So it might be better to just clean the cat out or replace it. Replacing it with an aftermarket CARB approved cat will save you money over the factory cats.
@@WarPaintOffroad Yup - This is for an offroad rig. I noticed that the part comes with an o ring and a few other items but no instructions. Your vid doesn't show the install either. Where do the other parts go on the extender?
