I do think taking lead out of the gas was a good move, but still, I have never seen actual measured results of environmental damage. You have to understand the political motivations behind such movements too. You are not considering that at all,---and these anti-free market pricks are very tricky.
The point of a cat is to charge rediculous prices for something that doesn't really do shit except cost you money....by restricting your motor then when they go out you gotta spend a shitload....plus you gotta fuck with o2 sensors as well. You can cut them out and cut you some pipe with the o2 sensor threads and weld that back in so you don't throw sensor codes
Does the downstream o2 sensor have any effect on the way the engine runs if you dont weld on a spacer for the o2 sensor or will it run fine if it throws a code?
I disconnected the check engine light altogether and I only hook up the OBD scanner when I notice something is off. I grew up driving cars made before OBD so I don't mind waiting for a symptom before doing a diagnosis/scan/troubleshoot. Don't need a light.
My 2005 Mercedes E320 CDi had two cats, a big ass one behind the turbo and a secondary one further down the system, both gone and ZERO smoke, only an extra poke along with a very welcome increase in mpg's. Strangely there was not one O2 sensor on the whole system so no dash lights either. Engine is happy and so am I. Greta maybe not so much. Done it in every diesel car I've owned and the emissions test are always very low during the annual MOT test we have here in the UK. Go figure...Petrol (gasoline) cars it's a huge no no though, impossible to pass the emissions test without a cat fitted unless your car is historic or pre 1991.
I don't know if it still is, but it used to be a federal crime in the US to try and pass off a punched cat as legit on inspection. In those states mix up some high octane fuel that will send more unburnt fuel into the exhaust thus burning up the cat, then if you fail inspection there are no tool marks or signs of tampering. By the way most of the time a hot exhaust will still pass, I passed with melted down cats for about 5 years before I had to start over.
Ok. So how does one get the car back to normal exhaust decibels?? On something designed for quiet and confront such as say...a 2000 Toyota Avalon...how would a person get it quiet again? Can someone stuff inside some kind of stainless wire mesh or steel wool material? Any ideas? Thanks
Not necessarily, all a code is your car is detecting something. So I have a missing sensor somewhere for my tire pressure, the light is always on (my alignment is fucked however all 4 can be at over 32 psi and the lights still on) but when I blow a tire or get a nail (I don’t notice usually till the next day) any time there’s a drop in psi that’s more than unusual it’ll go off that moment it’s happening. So technically as long as there’s no other issues with the car all it’s picking up is “hey there’s to much bad exhaust exiting the vehicle” when in reality that code was already there to begin with but now instead of being a filter it’s a clogged hole letting bits of exhaust by pass. If you haven’t found it already there is a spark plug adapter that will fix the issue
I thought the sensors went back to the computer and adjusted how the fuel injectors work or something like that. I thought they did more than just tell the computer what it's reading. I thought they actually made adjustments according to them? 🇺🇸💪🏼👊🏼🤙🏼
@@c_mac7773 they do. I had some bad ones and my truck was running like a piece of junk. Smoking black, had carbon coming out of the tail pipe. Real sluggish. I changed them, reset the computer and the truck started running right again. So it defintly does more than just what folks say
@@c_mac7773 what are those? Because my truck has over 400,000 mi and my converters are clogged up. I keep getting a catalyst efficency Below threshold. Soi know it's bad. But was told if i gutted it then it will throw codes.
@@Mgebabyjioget one for your rear o2 sensor. If you have multiple cats, you want to put a o2 sensor spacer on every rear o2 sensor. Basically any o2 sensor that is behind/after the cat should get a spacer. The o2 sensor after the cat is the one that causes check engine lights.
Hmmmm, I use magnesium to start fires with. I thought it was other heavy metals like platinum, palladium, and rhodium that the cat honeycombs consist of.
@@GearsAndTech I just finished taking out my honeycombs out today out of both headers. What’s odd is that they weren’t like anything I’ve seen anyone else taking out. I thought it was going to come out like rocks. Instead, it came out in like metal sheets that were wrapped round and round on itself. Also, it was magnetic because it was sticking to my drill magnet that holds screws and such. They were OEM as well.
@@GearsAndTech it was out of my 2003 325CI parts car. It had some weight to it so it wasn’t aluminum, but I guess it couldn’t be aluminum either since it was magnetic. I thought that crap would break up easily like I’ve seen from everyone else doing the same. NOPE, this was a PITA.
Does the engine computer need the O2 sensors to calculate fuel efficient operation? Will the air fuel mixture be messed up.if the catalytic converter is removed since it is hooked to a computer?
I have a 01 tundra with 241k on it and year and years ago when it was still my pops he actually had a fire start from a plugged cat. So yeah I'm gonna be gutting both the cats on my truck now cause fk that and fk my resonator lol
if i just want it to be a little louder can i just drill a couple holes? or do i need to hollow it out completely? i don’t want it super loud just a little louder
Usually this will cause a hissing sound, and depending on where your cat is it could also let carbon monoxide and other toxic fumes into your cars cabin if you're idling while stationary, and these chemicals build up in your body over time so avoiding them in the first place is a great idea. Plus holes before the muffler will be much louder than you expect, because they aren't being muffled, a few holes in the cat may end up louder than hollowing it, or replacing it with a straight pipe. I'd recommend drilling holes into the muffler, near the far end of it and checking how loud it is with each hole by starting the car every time
@@GearsAndTech It may be possible for loose particles from the cats to actually make it to the engine values during operation. I don't work on 4-stroke engines, but I do build 2-stroke engines for a living. I thought it was impossible, but I have seen sand enter an "exhaust can" on RC cars in sand dunes, and fill the engine up from the exhaust side of the engine. I would think it was "sound waves" bouncing back, and carrying the dirt into the engine. A half gutted cat will still change direction of the sound waves, and they do have a force.
@@EarthSurferUSA I had a geo storm back in the day cats got clogged I hollowed it out...BUT ...i didnt get all the pieces out ...and when hooked it all back up the particulates got sucked back into the engine ....good by valves car never ran right after that .
My e46 has a lot of blie smoke that is coming out of the exhaust after i put a new cataloc converter. Each 200km of driving, the check engine light is showing up. I delete it and comes again. It gives a code about cataloc converter. If i replace a proper cataloc converter, will the smoke be more less?
Well since my gasoline tank evap valve has got a permanent check engine light on that i could care less about, this will just match up perfectly and i wont even think about the new hidden code.
usually your fuel economy goes down. And unless your car has forced injection (turbo or SC) you likely will lose low end power. What you gain, is higher top end, and a really cool sound when you step on the gas!
The catalytic converters in Canada are not made with magnesium. That is absolutely ridiculous. But they are different from the cats on American cars. The Canadians found that if you filter your exhaust through maple syrup that would help them win the Stanley Cup. So yes the cats in Canada are filled with maple syrup and no they don't work at all. For anything.
That's a tough one. Here in Alberta you can't In fact, you can buy a brand new truck off the dealership with no mud flaps, and on the way home get pulled over by the police for not having mud flaps. You can't sue the dealership then So, it's unlikely you can sue a shop for no cat. You always have the right to do a pre purchase inspection at a shop of your choice before buying.
Just so people from Pa know..the law states that the cat HAS TO APPEAR STOCK ..SO AS LONG AS YOU DONT HURT THE SHELL OF THE CAT YOU CAN DO THIS..I've lived in Pa my whole life to all my cars had this done ive never had an issue with inspection
Beware, gutting your converter may damage your engine on vehicles later than 96 due computer pollution sensors which monitor upstream and downstream exhaust gases. Your vehicles computer use the data to adjust air/fuel ratios and can cause your engine to run too lean or most likely rich which can cause poor fuel economy and excess carbon buildup.
You’ll need what’s called and o2 Fowler plug adapter to pull the o2 further out of the exhaust stream so it read correct. People using race pipes use these where there is no cat in place at all.
Ya, it's not as simple as the guy in the video puts it: with all the tuning and other exhaust mods you would have to make for it to be safe for the engine and to get enough horsepower for it to be worth it (especially on vehicles with smaller engines), but it is worth doing if you got an old cat in a lot of cases just because they can get expensive. If you're buying a new car fresh of the lot, maybe leave it in till its used up though, that's how I see it....
@@darronpattel personally I think it does more harm than good. It’s perfect if you need to look stock, but with a hollow barrel larger than the diameter of the pipe coming in and out, it creates a sport for turbulence, which can create heat from exhausts that can’t get out and swirl around inside the gutted cat, and or slow your exhaust flow down, which can be why some people lose power.
@@Subi_doo Exactly, its stuff like that he shoulda been mentioning. I'm a welder because my dad was a welder by trade so I made my own straight pipe in less then an hr and im not even a pro welder or anything. So if you get the right person to do that, tune it and maybe put some new headers on then in most cases ur good, but he mentions none of that in the vid.
@@Subi_doo For my car with making the straight pipe myself, the tune, and new headers; it cost me around 4000$ CAD with labour. Even with that costing more then getting a new cat, ill never have to get a new one again.
lol. If we are being fully honest its rhodium, palladium and platinum. But, who cares what it is? Dont breathe it in, and just knock it out to get the desired effect. Some people probably have dead mice, leaves, and dog food in theirs!
Magnesium? It's ceramics with precious metals like platinum radium in palladium , I don't know what you got your info but magnesium is not a precious metals in cats and it's not precious its very similar to aluminum. If your going to make automotive education do research before schooling folks and magnesium dust isn't "toxic" per se obviously dust or fumes from melting is not good for you to allow to enter your respiratory system and excessive fumes from welding it can cause flu type symptoms but dust isn't going to do that.
I'll see if I have that bag of precious metals anywhere still. Are you willing to put your money where your mouth is? I'll shake the bag up to get a good cloud of dust, then you just need to huff that dust for 1 minute to show all the viewers at home how safe it is
Lol. I was thinking about making a pro tip video of how to protect your cat from being stolen But I guess if you steal a few you don't care when yours gets stolen
All this emmisions and computer crap on cars is all BS... Just a way to make more $$$$ from consumers. Ive had it with all of it I'm looking for a nice old machine, pre-emmisions that's been redone modestly to buy.
Removing it completely without installing a pipe or something in it's place will, depending on how short this makes your exhaust that is. Some turbo vehicles lose a bit of power because the turbo will not operate at it's full potential, and unfortunately some older (as in 1996 and older) may go into limp mode, which will cut your horsepower down significantly, among other things. But generally, if the catalytic converter is clogged it will actually restore power if you do this
@@Yixdy A clogged cat, (and even some new ones IMO), will raise engine temps a lot, (even if the engine management system controls the water temp on your gauge). You will actually increase the life of your engine by reducing the temps if that is a problem. If your car runs great when cold, hammer it and it goes,---but loses that after it is warm, and you have some mileage on the car,---put on the top of your suspect list, "clogged cats". You also probably notice your heater blowing hot air, (from cold), real fast, and quite a bit of heat under the hood when you open it after operation.
What are you even talking about. Don't hear something that I didn't say and then tell me I don't know what I'm talking about! I said as cars get older the cat stops working and gets plugged up. I haven't seen many new cars with a plugged cat. Seriously though, clean out your ears and listen to the words that are coming out of my mouth next time.
Catalytic converters have been around since the mid 70’s, we always gutted them back then cuz we wanted less restriction, Now they design the control of the engine around them so you are stuck maintaining them when they fail, and they do fail often

Yes, milage and power will increase. The ones that say you lose low end power need to research exhaust back pressure and exhaust velocity.
Magnesium? No, they have Platinum, Palladium & Rhodium. Maybe Canada's converters are Magnesium.
We get the best of everything
The catalytic converters in Canada are not made with magnesium. That is absolutely ridiculous. But they are different from the cats on American cars. The Canadians found that if you filter your exhaust through maple syrup that would help them win the Stanley Cup. So yes the cats in Canada are filled with maple syrup and no they don't work at all. For anything.
catalytic converrters dont use magnesium. They use Palladium, Rhodium and Platinum...
Can small shop dealer sell you a vehicle with just straight pipe muffler, I just bought a box truck without the cats. Can I sue them for it ..
That's a tough one. Here in Alberta you can't
In fact, you can buy a brand new truck off the dealership with no mud flaps, and on the way home get pulled over by the police for not having mud flaps. You can't sue the dealership then
So, it's unlikely you can sue a shop for no cat. You always have the right to do a pre purchase inspection at a shop of your choice before buying.
Bag of magnesium for "recyclers" right 😂 😈
Just so people from Pa know..the law states that the cat HAS TO APPEAR STOCK ..SO AS LONG AS YOU DONT HURT THE SHELL OF THE CAT YOU CAN DO THIS..I've lived in Pa my whole life to all my cars had this done ive never had an issue with inspection
Beware, gutting your converter may damage your engine on vehicles later than 96 due computer pollution sensors which monitor upstream and downstream exhaust gases. Your vehicles computer use the data to adjust air/fuel ratios and can cause your engine to run too lean or most likely rich which can cause poor fuel economy and excess carbon buildup.
You’ll need what’s called and o2 Fowler plug adapter to pull the o2 further out of the exhaust stream so it read correct. People using race pipes use these where there is no cat in place at all.
Ya, it's not as simple as the guy in the video puts it: with all the tuning and other exhaust mods you would have to make for it to be safe for the engine and to get enough horsepower for it to be worth it (especially on vehicles with smaller engines), but it is worth doing if you got an old cat in a lot of cases just because they can get expensive.
If you're buying a new car fresh of the lot, maybe leave it in till its used up though, that's how I see it....
@@darronpattel personally I think it does more harm than good. It’s perfect if you need to look stock, but with a hollow barrel larger than the diameter of the pipe coming in and out, it creates a sport for turbulence, which can create heat from exhausts that can’t get out and swirl around inside the gutted cat, and or slow your exhaust flow down, which can be why some people lose power.
@@Subi_doo Exactly, its stuff like that he shoulda been mentioning. I'm a welder because my dad was a welder by trade so I made my own straight pipe in less then an hr and im not even a pro welder or anything.
So if you get the right person to do that, tune it and maybe put some new headers on then in most cases ur good, but he mentions none of that in the vid.
@@Subi_doo For my car with making the straight pipe myself, the tune, and new headers; it cost me around 4000$ CAD with labour.
Even with that costing more then getting a new cat, ill never have to get a new one again.
Right bro..love from Pakistan.
The moral of this story is. “ u only have to replace ur catalytic converter IF u get caught “ 😂😂😂
Yes
Rhodium Palladium and platinum
I want that ssei
Looking back, it would be sweet to have it now too
Not illegal for dedicated race/rally vehicles!
Off road use is no problem at all
It's not magnesium jerk. It's platinum that why they will pay you high bucks.
lol.
If we are being fully honest its rhodium, palladium and platinum. But, who cares what it is? Dont breathe it in, and just knock it out to get the desired effect.
Some people probably have dead mice, leaves, and dog food in theirs!
Magnesium? It's ceramics with precious metals like platinum radium in palladium , I don't know what you got your info but magnesium is not a precious metals in cats and it's not precious its very similar to aluminum. If your going to make automotive education do research before schooling folks and magnesium dust isn't "toxic" per se obviously dust or fumes from melting is not good for you to allow to enter your respiratory system and excessive fumes from welding it can cause flu type symptoms but dust isn't going to do that.
I'll see if I have that bag of precious metals anywhere still. Are you willing to put your money where your mouth is?
I'll shake the bag up to get a good cloud of dust, then you just need to huff that dust for 1 minute to show all the viewers at home how safe it is
Tell that to the asbestos industry
Does this work on eco boost?
Turbo charged engines especially like to have free flowing exhausts
@@GearsAndTech that’s great to know saved me 700$ thank you💯😮💨
Just went out to delete the cat on this old Nissan truck I just bought, and it's already gone and had a pipe welded in it's place 😂
even better
Not magnesium it is platinum
Where are you from?
Canada
Dont ruin a good cat. The air smells like death
@gearsandtech this is what I'm having a problem with. The fumes. Any help on how to keep them down?
pro tip: steal your own catalytic converter
Lol.
I was thinking about making a pro tip video of how to protect your cat from being stolen
But I guess if you steal a few you don't care when yours gets stolen
@@GearsAndTech won’t they be surprised that they done spent an hour cutting out empty cans ?
Cats don't have magnesium. They have cordierite a iron, mix alum, manganese in them.
All this emmisions and computer crap on cars is all BS... Just a way to make more $$$$ from consumers.
Ive had it with all of it
I'm looking for a nice old machine, pre-emmisions that's been redone modestly to buy.
I hear you.
Yup, every system in the car is tied into it - $$$$ at every turn
Yea and litterly all the problems that they say can be fixed by a tuner lol
Ima do this until I learn how to weld
gonna cost 1000$ to replace both precats not even the 3rd cat, i want to learn how to weld stainless
Welding stainless is a special skill not everyone has
No Cats on my 1967 Buick Riviera. Catalitics converters came on the market in 1975.
Will this hurt my car tho?
Removing it completely without installing a pipe or something in it's place will, depending on how short this makes your exhaust that is. Some turbo vehicles lose a bit of power because the turbo will not operate at it's full potential, and unfortunately some older (as in 1996 and older) may go into limp mode, which will cut your horsepower down significantly, among other things. But generally, if the catalytic converter is clogged it will actually restore power if you do this
@@Yixdy A clogged cat, (and even some new ones IMO), will raise engine temps a lot, (even if the engine management system controls the water temp on your gauge). You will actually increase the life of your engine by reducing the temps if that is a problem. If your car runs great when cold, hammer it and it goes,---but loses that after it is warm, and you have some mileage on the car,---put on the top of your suspect list, "clogged cats". You also probably notice your heater blowing hot air, (from cold), real fast, and quite a bit of heat under the hood when you open it after operation.
Never will pass state’s inspection
No, if you have state inspections this isn't the mod for you
Will my gas mileage get horrible?
It will improve.
how about a hammer drill chisel
That would work. If it's long enough
This is not the function of a cat, it reacts with the worse gases, through catalytic activation, turning them to less hurtful gases, still sweet video
Ya turns it into big dollars for someone, def not the vehicle owner
I'd like to inhale the pollution without catalysator 😋☠🌲👍
Right? If it is so dangerous to handle, how is it good to breathe with exhaust fumes lol
Literally just bash ita gutts out and clean it up.. install back and call it a day????? Mine is already rattling
Yep. Pretty simple
It's Paladium NOT magnesium. People don't steal them for magnesium😂😂😂😂😂
Not older cars!!! Be more knowledgeable.
What are you even talking about.
Don't hear something that I didn't say and then tell me I don't know what I'm talking about!
I said as cars get older the cat stops working and gets plugged up.
I haven't seen many new cars with a plugged cat.
Seriously though, clean out your ears and listen to the words that are coming out of my mouth next time.
Catalytic converters have been around since the mid 70’s, we always gutted them back then cuz we wanted less restriction, Now they design the control of the engine around them so you are stuck maintaining them when they fail, and they do fail often
Easy moneu
👍👍👍👍👍👍
Yes
Did u just hit a bird
I don't think so
