How to Pass Emissions Without a Catalytic Converter!

[@gabrielcornejo238]

Nice advice. Here in Illinois from 1996 are required to pass emissions tests but they only check on OBD scanner. So this device might help faulty catalytic pass emissions.

[@AutoAutopsy]

that's how it is here in my county in AZ!

Ive got a defouler on all 4 of my vehicles and never had a drivability or emissions testing or CEL problem and I've had the very 1st one on for bout 8 yrs

Here, in a 9 county area on the Colorado front range, they do dyno testing so no matter what tricks you employ, what comes out the pipe is what passes or fails.

[@AutoAutopsy]

:(

[@Executiveinvestments-]

So that’s even easier if you have a newer car. All cars that run correctly will pass without a converter. That’s why they went obd route.

[@03kwam65]

Not in va they dont dyno

[@uscar17]

My question is, how does the defouler work ? Does it just let less exhaust gasses to the O2 sensor, making it think that the cat is doing its job ?

[@AutoAutopsy]

I believe that's the idea; great question

[@uscar17]

I would guess so, since it doesn't appear to be plugged in to anything

[@Bassmasters1984]

Pretty much does work tho I did it on my f150 and I live in cali

[@onehappydawg]

After looking through all these comments I can tell that a lot of people do not understand that laws and regulations change from county to county and from state to state. This is definitely the case when it comes to almost anything to do with emissions. You may live in a county with the most strict emissions regulations in the whole country and right next door in the next county they couldn’t care less. There are lots of places across the country that do not even do emissions testing.

[@heinargo]

Check engine or no check engine, but what about carbon monoxide and hydrocarbon readings? I am not sure that even Saab B20x and B23x engines could pass emissions test (in Estonia at least) and they are very clean running engines.

[@brandonstolberg8806]

I think a lot of emissions laws are crap. In the early '90's while living in California, I had a friend who worked at an emissions shop. Just for kicks we ran a bunch of tests one night, with emissions equipment, and without. This shop had a dyno and did load test emissions. We tested a 1990 Ford F250 with the 460 cu. in. big block, a 1988 Toyota Celica, and a 1993 Mitsubishi 3000 GT. As expected, the removal of all the emissions equipment produced a noticeable gain in horsepower and torque in all vehicles. Unexpectedly, they also produced cleaner tailpipe emissions under load with the emissions equipment removed. May not be the case all the time, but that is what we experienced.

[@AutoAutopsy]

Lol that’s interesting

[@darrenrauschwebdesign]

The converters are contributing to global warming. They turn carbon monoxide into carbon dioxide and although this reduces smog in dense urban environments, it also heats the environment. sequoyahsteminstitute.org/blog/2019/2/1/the-catalytic-converter-its-pros-and-cons-in-the-modern-world

[@thothheartmaat2833]

also the general practice and advice given for how to get your monitors ready for a test is for everybody to go out and drive on the highway and around the city for hundreds of miles trying to get your monitors to set.. yeah thats how we lower emissions.. go drive around everyone..

[@marblox9300]

@@thothheartmaat2833 Yep, this country and all of it's STUPID rules are so full of shit. If no vehicle in the U.S. EVER got tested for pollution - the air that we are all breathing would be exactly the same as it is now.

[@KenzertYT]

My guess is they may have not had enough time to heat the cats up, the way the cats work (for anyone curious reading) is they get hot enough to catalyze (aka burn off) the unburnt fuel emissions, that normally didn't get burned in regular engine operation.

[@AikidoTubeSock]

Will/won't the defouler be detected during the emissions inspection? Even though the catalyst monitor will show as completed via OBDII scanning, don't they also do a visual inspection under the car to look at things like you O2 sensors?

[@AutoAutopsy]

depends entirely on where you live.

It depends entirely on where you live

[@SupercarBuilt]

You mentioned you have 2, 02 sensor locations. Do you put a defouler on each one? Or does it work with just the one you bought?

[@_pvn]

Only downstream requires the defouler, if your car should have multiple catalytic converters and/or they have different sensors, you'll need multiple defoulers. Don't go pairing these things in your upstream sensors. As an example my 4 cyl accord only has one catalytic converter and sensor downstream, so I only need one.

[@Bassmasters1984]

Top o2 sensor will stay in pipe second u use a de fouler u want the reading between the first and second to show a different reading being before cat and after cat the amount of gas should be less after going through ur car their for causing the de fouler to trick the car to thinking it has a cat

how to pass emission, you pass the lady doing the inspection $50 💀

[@juicem4700]

Will this work with corvettes

[@AutoAutopsy]

Should work with any car, to mu knowledge

[@Casino_flo]

Do you have a vette and did you try it??

[@thomasfletcher8710]

So do I need to buy 2 cause my car has 2 o2 sensors

[@AutoAutopsy]

it's needed for whatever o2 sensor comes after the catalytic converter

[@thomasfletcher8710]

Auto Autopsy well I want to take the catalytic converter right off and fabricate a down pipe and straight pipe it I have a 2010 Chevy impala right now I have everything chopped off right behind the converter and there was no sensor right there

[@fatjaysgarage]

Here’s some useful info.. the 2 sensors are called pre cat and post cat. The ecu takes both readings. To see how efficient the cat is. If both sensors get the same reading then it knows that the cat is not working... so this device would go after the cat to trick the ecu to think that the emissions after the cat are cleaner than before it

[@kiblerredneck1985]

@@AutoAutopsy Would it work for the O2 sensor before the Cat? I have 2 sensors on my bronco someone already deleted the rear o2 but the front 2 are reading bad. I just want to eliminate them and be done. Is that possible?

[@zacharyroth6582]

Would it work on an 04 vw jetta gls 2.0?

[@97bmxMOOKEYbmx97]

Yo I’m literally here to see if it’ll work in an 05 mk4 gti

[@AutoAutopsy]

i would assume so, depends on threading

[@kylekagaoan9453]

Did you ever end up trying it. I have the same problem for the same exact car

[@Cityj0hn]

Wait What? How does your exhaust actually remove the carbon monoxide and NOX without a cat though? Doesn't this show up on the emissions tests?

[@AutoAutopsy]

You missed the entire point of this video lol

[@tomsweeney5664]

My catalytic converter got stolen do I have to replace it? 2011 Honda element

[@AutoAutopsy]

yes lol

[@el-squanchi9456]

Sell it fast!! Cats are pricey af

[@haydens465]

So with an OBD1 car where I live they don’t do a plug in, they do a smell test. How would I pass that

[@AutoAutopsy]

i'd ask people locally, i don't know.

[@AyyItsJk]

Pass them a 20 and pray to god

[@DjDubStak]

State of IL do not test emissions on OBD1 vehicles 95 an older

[@johnedobor7435]

@BigSexe .

[@alanchan1772]

California smog visual inspection fail as tamper bung install on o2 sensor.

[@AutoAutopsy]

Lame

[@_baller]

Yeah California is different than any other state

[@NeptuneNick]

Would this help a car not run rich after buying a catless header

[@AutoAutopsy]

Sounds like that’s a tuning issue

[@NeptuneNick]

@@AutoAutopsy I haven’t gotten a header yet. I just saw forms on the car that it makes the car run rich

[@Mr.Lyric01]

Will it still work and not mess up your engine?

[@AutoAutopsy]

it shouldn't

[@proudmommy9]

Is it possible to need more than one of these?? I think my car needs 4!?

[@AutoAutopsy]

you'll have more than 1 02 sensor most likely (mine has 2), but you won't need this for all 4

[@jimcatx3090]

Only need them after the cat

[@Fee.1]

Auto Autopsy still won’t pass CARB right?

[@dmitrypravednov8518]

I did that and it worked but when I go pass 6k rpm than I get a check Engine light any idea why

[@AutoAutopsy]

check what code you're getting and go from there...

[@RickyKehoe]

Aye I cut one side of my catalytic converter so that it's loud. You think I can still pass emissions? I have no check engine light because I did it right

[@AutoAutopsy]

Lol, i don't know if there's a "right" way to cut your cat; depends on where you live and what inspections are like there.

[@RickyKehoe]

@@AutoAutopsy well, I mean I had a buddy cut it so it hangs but also so the o2 sensor doesn't go off. Not familiar with this sort of stuff so thought I'd ask

[@nicka5252]

Hey I got a p0057 code after installing this? Can someone help thanks

[@wolf.media98]

Still working now? I just bought a whole ass cat but that shit aint got a obd2 sensor inlet and I aint trying to drill into it either

[@AutoAutopsy]

Yes it never gave me any issues
