Pls Help: Catalytic Converter Missing In Exhaust Pipe / How To Remove Check Engine Light Originating From Bad/absent Catalytic Converter / Driving A Car Without Catalytic Converter (2) (3) (4)

Siena: I am going to gut my CATALYTIC CONVERTER tomorrow, God willing. I have thought it through, buying a fairly used CAT. is a No NO, and I can't wait for the time it takes to order a new one. But I think it is just going to work great. The Catalytic converter really isn't anything other than a chamber that holds special types of metal that reacts with your exhaust fumes, to make them safer gases. It doesn't impact your fuel consumption in itself. The reason why cars running without CAT. consume fuel is that the Oxygen sensor senses too much air and directs the system to throw more fuel in to balance the mix. So if you can reduce the exposure of your O2 sensor into the chamber of the CAT.; then you may actually prevent it from doing so. The trick to achieve this is simple; put a spark plug defouler before screwing in the O2 sensor. As for the theory of creating turbulence in the hollowed CAT. I think it is over exaggerated, the CAT. in itself isn't that big, The muffler will discharge the exhaust gas more quickly, without the CAT and hence you are not likely to experience turbulence but in fact steady flow. The idea of turbulence is based on the thinking that the car will generate more fumes than the mufflers can discharge instantly, which I don't think is the case. To further buttress this point, many cars made for outside USA markets don't even have a CAT installed in them. The only issue I am not quite sure of is the fact that some cars do need some back pressure, which the catalytic converter provides, but definitely not all cars. |

pls, I need help. I use a 2005 toyota matrix XR 4wd. I had a mechanic check on it & it was discovered dat d catalytic converter is absent. I have a 45 litre tank(dats what d manual says) but @ filling stations, d minimum fuel dats filled it up is 52L & I use it 4 approximately 10days( I only go 4rm my house 2 my work place everyday of d week,which is 15minutes drive). Some pple say my car's fuel economy is good, some say its not. This is my first car so I don't really have nothing to compare with. But the main issue now is dat the noise d car makes is much. Every now & den, pple ask me why d sound of d engine is so heavy. U don't have 2 be in d car 2 hear it. The body vibrates, I hear lots of wierd sounds. A mechanic told me It was d engine seat, they checked & say a damaged one & fixed it. It didn't change anything. Anoda one said my exhaust is leaking 4rm d site the catalytic converter was removed & I shld bring it 4 sealing by welding. I've not done dat yet, I jux need you guy's opinions cos I don't think many of these mechanics know wat they're doin. Thnx a lot in anticipation 4 yur prompt responses. |

When I got my car, the Catalytic converter was absent, meaning, the oxygen sensor was absent too. I bought an oxygen sensor, constructed the bung on the exhaust, screwed in the purchased o2 sensor and connected the sensor on its harness that was left hanging-unconnected. Without the Catalytic converter, the car mpg remains factory, proven by the last trip i did with the car last month. I dont know about the working of your engine management, but mine runs well, even better, without the Catalytic converter, as long as the oxygen sensor is still installed and connected. You need to find out how many o2 sensor and cat converter the car should have (google it). Then you check to know if the car still have the sensor(s), even after the removal of the cat converter. You didnt give us enough details to know if the car is thirsty or not. We need to know the distance from your house to office and how many minutes/hours you spend on traffic jams on your way to office (if any). Or you simply scan the car, whether you are getting the "check engine" light on the instrument cluster or not. Our mechanics and auto technicians can tamper with that bulb. Ikenna. |

Thnx Ikenna 4 d prompt response. Distance 4rm my house 2 work is like 4rm Egbeda 2 ikeja inside. I stay in kaduna( 4rm u/rimi to stadium) & there isn't much traffic most times( maximum of 5minutes in traffic, in total its 15minutes drive 2 work 4rm my home. I've had d car scanned b4 cos I had d check engine light & still have it- O2 sensor issues. The car moves well as testified by different drivers cos I've travelled with it-Lagos 2 sokoto, sokoto 2 benue. On one occasion I travelled 4rm sokoto 2 kaduna & used a full tank(45L), I got d reserve light as I entered K.D. So I don't really know if this is good economy. More contributions needed pls. |

thirdi: yes you can , Same thing happen to me sometimes ago i have to go to LADIPO market to get it. Go and buy loose and tight and not cut and join as popularly know by the mechanics. Its 15k as at 2014 but i dont know the price now Sorry bro |

@ nobody.. Do you happen to know anyone with large quantities of old catalytic converters?contact me via email obidevine@yahoo.com |

We should all be aware of the symptoms of absence of Caty converter in a vehicle 1. Loud noise when car is started and running 2. Dark and more emission from the exhaust 3. Increase in carbon monoxide making it difficult for u to breathe when u wind ur glasses down 4. Your exhaust is no more intact from visual inspection 5. Increase in fuel consumption 6. Car accelerating poorly |

KunleA2:how? Do they now steal catalyst inside port? Hold your agent responsible |
Re: Stollen Catalytic Converter by paul1980: 6:25pm On Jul 11, 2022 |
The caty converter indirectly reduced fuel and create velocity for the o2 oxygen sensor to sense previous exhaust jet |

Mine was stolen by my mechanic also sad |
