Haha true! :-D
WHAT IN THE WORLD IS HE TALKING ABOUT!!!!!!😨😬🤨🙄🤔🤕😧🙁🥺😟😦
@@shelbymyles8430 umm..catalytic converters for bikes. Can’t you read??
@@shelbymyles8430 🤣
I appreciate the different perspective! Nicely done!
I appreciate the feedback, brotherman! Haha I tried to come up with a way to make it interesting and scientific. I actually had to do a lot of research on this one.
Very well put together. Thanks
Thank you for the kind words, my friend. I'm glad you liked the video!
Great informational video! The science is pretty cool too!!
Thank you, Dakotaa Bookk! I'm glad you enjoyed the video! :-)
Great vid! I wish UA-cam was around when I was taking automotive class.
You deserve A LOT more followers!!
Thank you brotherman! I appreciate the vote of confidence. :-)
Very informative! Thank you!
I'm really glad you liked it, my friend. Thanks for the compliment!
Very nice and informative video indeed 👍👍👍 still thinking about cutting costs and getting rid of the Cat converter for the 2006 Honda Shadow Aero
Thank you Mohamed Kholif! :-)
GREAT vid and information thanks!!!
You're welcome, Simon! Thanks for stopping by.
Superb video. Explains it all
Thank you, Darren!
Thanks for the information
My pleasure, Marc. I'm glad you enjoyed the video!
Awesome ! :) Ty
Nice science class. Very informative. My cat WILL stay on my RC390. Removing it ain't worth the trouble with remapping, ECU stuff and all... A PWR commander 5 and the Akra slip-on it'll be for me and my RC. Thanks for the video man, great job.
Thank you Denis! :-) If eventually you do decide that you want to squeeze a little more juice out of your engine, there are some street legal MAPs or tunes that you can get to load into your Power Commander, usually for a small fee.
Absolutely, but make sure to add piggyback ECU, remapping or standalone ECU should be used. 👍
Stay safe
it depends where about the Flow sensors are , if they before CAT then its fine and don't need to mess with the ECU ...
@@oldfartuk No, remapping is required for the AFR and anytime there are changes made to intake or exhaust, retune is required.
the answer is YES!!
excellent
Thank you, friend!
I've got a 150cc SOHC Bike its exhaust has a Catalytic Converter and a heavy muffler
it has poor power output though from that massive back pressure..
11hp@ 7,000
a similar bike but an older model can do 14hp@8,000
if I replaced the exhaust, replace the carburetor and put a pod filter
can probably add 1 or 2 hp at higher rpm's maybe even more if replaced the camshaft with a Performance Cam
That's where the restrictive stock emissions parts really rob you: at higher rpms. Let us know how your project turns out, Jasper!
Bit random but if I cut out the cat of my stock downpipe, and replaced it with just a bit of pipe, and kept the stock end can on, would that change the sound at all? And would it harm the engine?
Great questions! So what you talked about doing will most likely increase the volume of the exhaust. I'm not sure if it will sound better, but in theory it should sound just a bit louder. As far as harming the engine: with the rest of the stock exhaust still installed, I doubt there would be any problems with your engine. If in the future you swap out the other exhaust components for aftermarket ones, be sure to get the bike tuned or install a piggyback ECU like a Power Commander or Powertronics or something along those lines to give you the ability to purchase a tune online and upload it onto the bike.
As this is two years ago what about the new ecu, I've heard that the ones on the meteor are learning ecu and as such can adapt to the change in the exhaust
Oh sorry for not responding sooner! Yes, adaptive ECU's have been around for decades in cars/trucks/vans/SUV's... I don't know enough about the motorcycle industry as a whole to know if they have plans to implement that technology into motorcycles or if they already have in certain models. I would imagine that in theory they would eliminate the need for piggyback ECU modules and tuning, however we've also been seeing companies like GM locking down the computers of certain models (like the new C8 Corvettes) to keep the performance levels within their predefined parameters. So I don't know if it would allow for such modifications or throw a code and prevent the motorcycle from working with anything other than stock running gear. I think I'll look into it! :-)
I have a 2021 Honda Cb350 single cylinder long stroke bike . 21bhp at 5500rpm and 30nm at 3000 rpm. Weights 190 kg. I unplug the O2 sensor and bike rode a bit better with slight increase in throttle response .but popping at downshifts . It just have a simple cat in downpipe below O2 sensor , ecu are not available for this bike as it’s new not even in Japan (Honda gb350) . I want to delete cat, should I do it or not for sound and a bit of power.
That's a tough call, brotherman. I don't know enough to give you sound advice one way or the other, but if you are planning on de-cating your bike: you may want to check into some motorcycle mechanics near you that would be able/willing to dyno tune your bike for you once you make exhaust modifications. That way your bike should be running smooth and not have any issues. Your bike sounds real nice though!
@@FaerodynMoto thanks brother, in India nobody does bike dyno tunes. I think I’m gonna delete it, if something goes wrong will buy new downpipe as the exhaust is in two pieces.
@@themechanicsingh4159 ahhhh, ok. Sounds good, I'll be checking for sounds clips on your channel when you do it! :-)
What is the music at the end? I know it from Yammie Noob's videos
Haha yeah- I'm not sure if it's a real song or if Yammie Noob made it himself, but I found it on UA-cam channel CodeBlack07. Do a search for the video name "Yammie Noobs Bike Build Series Intro Song (looped)"
I ride a Triumph Bonneville and some make a big deal out of the decat. I suspect the improvement is minimal but a lot of guys seem to do it. I bought mine with it done and now worry about state inspection. Plus I am guessing she burns more oil with this done? Not sure. Thanks.
Hmmmm... I honestly don't know about the oil burning issue but I understand your worry about passing emissions inspection. I'll bet your bike sounds awesome though!
It shouldn’t burn any more oil than it did before. It’s the exhaust that’s affected. Not the piston rings.
Thank you...well done...now I actually might be able to understand the Cal ARB executive order on my Z900RS
Thank you for your positive feedback, Michael Hartman! I understand CA can be a bit excessive in their restrictions? I hope you still enjoy your ride, brotherman!
I have a street bagger, Indian Vintage 111 ci . Is there a street legal cat I can get, If so, who and where can I get one?
I'm not too sure about Indians. I think that most aftermarket cats aren't made vehicle specific, but sometimes full exhausts will come with them already. You kinda need to know what you should get for your specific application. I would suggest talking to someone who either knows Indian motorcycles well or knows custom motorcycle exhausts well and ask them what to get. :-)
Sir removing catalytic converter from meteor cause any warranty related issues, or it affects engine, / any main stand issue? Because I also wanted to make same modification, please replay
Typically manufacturers will void your vehicle's warranties when you make modifications such as removing the catalytic converter. You would need to read through the warranty stipulations to understand what you can and can't do with your bike.
As far as how it affects the engine: without dyno tuning your motorcycle or without a piggyback ECU (like the Power Commander V) your bike could lose torque and run hotter as a result.
There are a lot of people who are de-cating the J-series engine in the meteor and classic ect with no issues I'm aware of
Damn did not expect to see my bike when I clicked on this lol
Haha nice bike bro! :-D
i wonder... where can i buy a new high flow cat or even a stock one for my model motorcycle? cant find anything in google. are they universal or something?
I've found most catalytic converters are sold as universal exhaust parts. It's up to us consumers to know what size (diameter) we need for our exhaust and have it welded in place (or weld it ourselves if we know how). Most motorcycle aftermarket exhausts don't come with one, but some do.
@@FaerodynMoto do u know what i need for 2000 honda vfr? I cant find any info, i might just remove it
Is it bad for bike to remove catalytic converter and instal regular mid pipe and add slip on? Thanks
Replacing the whole exhaust usually leads to your bike running too lean (too much air/not enough fuel). It also leads to a loss of power because without back-pressure the exhaust valves don't stay open as long as they should. That issue can be fixed by getting the bike tuned professionally, or you could install a piggy-back ECU (like a Power Commander or Powertronics) and purchasing a tune online that you can install yourself. An extensive aftermarket exhaust without a proper tune for it can lead to your bike running too lean, which generates too much heat and can lead to excessive wear on the drive train. Not recommended long term...
Ok, thank you for answering. So it is better not to touch anything. Bcs I was thinking tu put just a mid pipe with slip on
@@revieweverythingforyou282 Generally you can do just a slip-on exhaust and be fine. The minute you do the midpipe too you really need to get it tuned. :-)
Lol you explained global weather too.
As long as earth as been around
It's been mainly animals breathing out CO2
And the odd volcano or disaster.
But now on top of the volcanos we add to the mix all these compounds and freak out over record breaking storms and temps 😂
Haha yeah global warming is bs. They've been trying to convince us of "the end of all life as we know it" going all the way back to the 80's. They've revised their prediction for when that will happen several times already... 😄
@@FaerodynMotoDude, they been doing it since the 1970’s. Back then the Chicken Little alarmists were screaming about global cooling.
if I remove the cat but I still want the stock canister attached, will it change the sound? will it be noisy
If you just replace the catalytic converter with something like a straight pipe then yes- the volume will increase, but only slightly if you keep the rest of the stock exhaust. It won't be too loud.
@@FaerodynMoto some claims, there gonna be a bassy sounds from the exhaust and i want that...i hope my 180cc will sounded like 400cc ducati hehe.. btw thanks for the reply..

@@miguelpaneda1607 No problem, Miguel. Good luck!
Hello! My sr50 2020 is completely stock and my exhaust is glowing red in catalyic converter area. Is this normal or not. Can someone please answer.
@Roki Leo: Hey man, thanks for your question. Your SR50 is a pretty nice bike! I have to say that in my limited experience I have never noticed my exhaust glowing after riding, and I don't think that it is normal for your exhaust to glow. It may be a fuel issue (bike running lean) or improper ignition timing. I would definitely suggest taking it in to a shop to get checked before your issue causes damage. Here are some links that I hope are more helpful:

@@FaerodynMoto do you have ig where i can send you a picture of a glowing part of exhaust
@@rokileo1309 Unfortunately not. The only social media accounts I have are Twitch, Discord, UA-cam, and Rumble at the moment.
I took the cat out of my 2018 Road King. It’s okay because it self identifies as an ATV and ATV’s don’t need cats since they are off road vehicles.
@@FriedPi-mc5yt haha love it!
Do high air flow catalytic converters increase fuel consumption?
Yes, but only a little. Typically any time you increase the airflow through the engine, the bike will start running lean. To prevent this, you can get the bike tuned or tune it yourself. Some bikes come with adaptive ECU's that automatically compensate for changes made, but the end result it the same: more fuel added to offset the increase of air. The increase of fuel used shouldn't be too noticeable from just one modification though. It's not until you fully open up your intake and exhaust that you will really start noticing a big change.
Lower the music, raise the volume on your voice
Good feedback, thank you!
hey!! I own ktm rc 390 and I removed the cat and installed a new exhaust and pipe,does removing cat affects badly to the engine? or do I need to change anything to the motorcycle to not cause any problems for removing cat? can u please answer this?
1.) Ok, so in short: a full exhaust modification like that can *potentially* lead to your bike running too lean (not enough fuel for the amount of air going through the engine). If your bike runs too lean, you might notice your engine temperatures go up high, which can lead to excessive wear and tear on the engine. It can also cause premature detonation of fuel in the cylinder, commonly referred to as engine "knock".
2.) There are a couple of solutions to fix this issue:
A.) You can take it to a motorcycle shop near you that can tune the bike specifically for the modifications you have made
-or-
B.) You can install a piggyback ECU (like a Power Commander or a Powertronics) and either purchase a tune for your modifications, or have someone who knows how to tune a motorcycle do it for you.
@@FaerodynMoto bro it is not full system,it is just bend pipe that starts to connects from where cat is removed, does it change anything? is that still a problem,sorry to bother u, can u answer me?
@@sarcasticdude23 it is alright to ask, I am happy to help you. :-)
If you only replaced the catalytic converter with a pipe (but *not* the rest of the exhaust), your RC390 should be alright. Just keep an eye on the engine temperatures and how your bike runs.
@@FaerodynMoto Thank u bro 🙏 love from india
I took the Cats off my Foxbody and gained a whopping 7hp.. a little louder.. was it worth it? Meh, it's something I can say if someone asks me really.. I have a 2020 Ram with headers and kept the cats on because of the extra expense and nothing really to gain.. idk
Nice! I like foxbodies. Matt Farrah did a really mean looking black-on-black build with his for The Smoking Tire. So you went catless- and you didn't see that much bump in power? Good to know man, thanks for the info.
@@FaerodynMoto it's an 88 and has 235hp but 325 torque.. it's a torque monster. I'm thinking about swapping the motor for a coyote 🤷
@@macwiller2105 Yes! I really like the Coyote, imo it sounds much better than the LS and the Hemi. If you're going to get a brand new one, there are crate motor with ECU kits for around $10k-$12. I was thinking of getting one for my daily driver eventually.
Nice video. How about turning DOWN the effin' background music so we can better hear your voice?
Lol ok, my bad. I'll be more mindful of my volume levels in future videos! :-)
Can I take it out of my v4 panigale ?
Oh, that's a really nice bike! I would imagine you could, but I also know those bikes have a lot of tech on them that can detect changes like that and might cause issues. I would suggest talking to a service technician either from a Ducati dealership or from your local motorcycle mechanic shop and see what advice they can give you first before doing any mods to your exhaust. Also check your local laws to see if it is legal, just in case.
Extremely informative video but the music was way too loud and highly distracting.
Ok, thank you for the heads-up! I'll lower my music volume levels from now on.
So I’d it going to damage the bike? That’s my only question
You're bike won't blow up, but I would strongly urge you to get it tuned. If you don't, it will run lean/hot which will cause excessive wear and tear on the engine over time.
Very informative video! Though I have experienced a cat theft on my Ranger F150 (now fully guarded with deterring toys), not sure if I want the same on my bike.
I have a 2020 CFMoto 300SR, to be paired with a full system (w/ high flow cat) IXIL can, which sounds like Matador on steroids XD But do I still need a fuel tune for her or just run as stock configuration?
Since that ain't a car with Turbo or anything to kick in, high flow cat on a bike is prehaps different from my understanding. Thank you, regardless.
Edit: TLDR should I slap a full system exhaust (w/ high flow cat) on my bike without tuning? A straight pipe definitely will need, but what about a high flow cat? Thanks a ton!
Hai Nhat Phung - Thank you! I'm glad you enjoyed it.
So on the topic of *tuning after a major exhaust overhaul*, here's the exhaust experience I've had: I have swapped a cat-back exhaust on one of my cars, a full header-to-tip exhaust on my other car, and now a full exhaust on my motorcycle.
It has been my experience that when you modify air flow without a tune, the performance change you may see is a bump in horsepower but a slight drop in torque. So you lose some low end grunt, but gain some high end pull. The danger comes if it starts running too lean: the engine can overheat, have knock issues, etc. Every situation is different, so proceed with caution.
If you plan to swap your exhaust without a tune, I would suggest testing things out carefully at first- maybe a few trips around your neighborhood so if you have to shut the engine off and push, you're not far from home. I hope that helps. :-)
Pt2- So to summarize: it should be ok, just take it easy at first and test the bike out to see how it runs without a tune. If everything looks good, ride on! 🤘
@@FaerodynMoto Thanks for your useful information!
So...in short a tune is also needed to make sure my baby won't running lean, either 4 wheels or 2. Oh well, if wishes are horses.
@@hainhatphung1371 You can still do a slip-on exhaust for your bike or swap out the muffler(s) on your car if you want to change the sound, that usually doesn't create any problems. A full exhaust, however, may require a tune.
1)Can we driill out catalytic converter.....??
2) is decating harmful to the normal rider....since he is around his bike most time??
1.) Air tends to take the path of least resistance. If you drill holes in the catalytic converter to improve air flow, then the exhaust gases will flow through those holes the most- so it would drastically reduce the cat's effectiveness at eliminating CO, NOx, and unspent fuel.
2.) The more a person is exposed to carbon monoxide, the more of an impact it will have on their body.... BUT motorcycle/car/truck racers are exposed to it when they race and they're ok... so I think you'll be fine without a cat as long as you're not running your bike in a closed garage.
@@FaerodynMoto If I drill holes in the catalytic converter will the exhaust eventually also be louder?
@@notquackyminecraft7999 If you're asking about drilling out the core of the cat, I'm not sure. It *might* get a little louder. If you're asking about drilling holes in the housing, then yes! I've seen people drill holes out the sides of their cats before, but they complained that it got obnoxiously loud and sounded like they had an exhaust leak rather than an aftermarket exhaust.
I think keeping your stock cat is the least we can do to help the environment.
They really have improved air quality!
Too much details on chemistry which no one cares , guests most people here just wanna know how loud and more power gain for deleting catalytic converter
I can help you with the big words if they're giving you trouble.
,the unit is a hypocritical Narsasist,,lol
Lol you ok bud?
Bloody annoying background music.
What would you suggest?
@@FaerodynMoto i would suggest thst there is no need for background music given the style of video. Mabye if it was a travel documentary yes. I found it distracting and would rather focus on what you were trying to teach as it was somewhat complex. Well done though 👍
@@brainspace3133 Hey thanks for the honest feedback Brainspace! I appreciate hearing from you so I can make my videos better. I only have my crummy laptop speakers to judge volume levels, so it's a little hard to set them just right for all speaker/headphone types. I think the music was a bit loud in this one though, so I've since lowered the levels of all background music/sound effects to not over power my voice. I'll also make sure not to use these songs again! :-)
Would have been a great video if not for the completely unnecessary distracting ridiculous so called music !
Thanks for the feedback! In the 4 years since I uploaded this video, I have learned to keep the volume of any songs I add to my videos down to a more reasonable level. :-)
Terrible music and should be labeled catalytic lesson
Thank you!
NO!
Right? 👍
