If a catalytic converter is removed on any car that was made after 1994, there will be problems with emission controls. Discover how the oxygen sensor will get messed up when removing a catalytic converter in some cars with help from an ASE-certified mechanic in this free video on auto repair and car performance.

    yea, that guy smokes a lot of bud.

  2. zech007 says:

    it it has 2 o2 sensor, one at the front and one at the back of the catalytic converter then you can’t if theres only one that is located in front of the cat converter then you can…

  3. RobertGary1 says:

    No. This is false. The rear O2 sensor has nothing to do with air/fuel mixture. The rear sensor is only to determine the efficiency of the cat. If it shows the cat isn’t working well you’ll get an “inefficient cat converter” code. Only the front O2 sensor affects Air/Fuel mixture.

    I have a 2001 S10 Chevy, very popular in my area. I want to get rid of the stock CC and maybe replace it later down the road when I find a decent one for a decent price. There is only a O2 Sensor in the rear of the CC. If I remove it and just put a 2 foot pipe there what will happen? Im not sure.


  5. RobertGary1 says:

    If you remove the CC that engine computer will detect that there is not a drop in O2 voltage between the exhaust manifold O2 sensor and the rear cat O2 sensor and will throw an “inefficient cat” check engine light code.

  6. elitecssplayer says:

    So what do you suggest I do? remove the rear sensor and get rid of it ? lol

  7. RobertGary1 says:

    Sure. You’ll have a check engine light on. But I assume that if you can remove the cat anyway you must live in a state that doesn’t inspect that type of thing.

    An aftermarket ECU.

    I have my o2 sensor mounted on my dump pipe.

  10. CHOPERUS23 says:

    a mechanic, who smokes bud? no way dude LOL

  12. CSilva76 says:

    so i wont take my bike Catalytic Converter =((

  13. bulltexan1 says:

    If you create an “artificial” voltage drop along the 02 sense wire,,then this system can be defeated,,and then yes,,,you could remove the CC altogether.

    Now,,,to come up with a better AC system……………………….

    Haha that guy need to lay of the maryjane before making videos.

  15. TheChevyguts says:

    what if you o2 sensors are bad already got a 01 one chevy 5.3

  16. crazymxboy says:

    How much can I get for a stock 99 cavalier cat I wanna get a high flow I also have made a cat back exhaust using a 3a racing tip

  17. autolover3 says:

    dumping more fuel in wont hurt it. itll just run more like shit. runnin LEAN will hurt it

  18. GirlyGirlMs says:


    right thats what i was told so this means if your rear o2 is in front of the secound catalytic converter you can remove it and no check engine light.

  19. G3kRay says:

    @RobertGary1 the rear02 makes very minor corrections to fuel trim on some vehicles

  20. G3kRay says:

    @bulltexan1 dont think that will work.

  21. GMSilverado says:

    @RobertGary1 No your wrong acutally depending on the year, the downstream o2 sensor has the greates control but it is what the up stream sensor looks at.. Depending on some things.. I can have up to 33% of the control.. don ‘t assume thing…. always check things out first and know whats going on..

    i think he is on weed.. ๐Ÿ˜›

    I wish i had this guys personality

  24. topedgar says:

    Always keep a catalytic converter ๐Ÿ™‚ 1. saves you a fine on some states 2.Fuel mixture since some of your vehicles have the Oxygen sensor right int he catlytic converter. 3. I know that you can bypass the catalytic converter but why go into the trouble of doing so when you can just replace it for a new one.
    PS: A new catalytic converter cost from $72-700, and the fine in some states for not having a catalytic converter is $1500. Remeber a catalytic converter does go bad often, fines come often

  25. topedgar says:

    Remove the catlytic converter ๐Ÿ™‚ = Clean air Act federal offence with a fine of $25k.
