Should You Remove Your Bike's Catalytic Converter? 

Haha true! :-D

WHAT IN THE WORLD IS HE TALKING ABOUT!!!!!!😨😬🤨🙄🤔🤕😧🙁🥺😟😦

@@shelbymyles8430 umm..catalytic converters for bikes. Can’t you read??

@@shelbymyles8430 🤣

Thank you brotherman! I had fun learning about all that stuff in my research, I was hoping my viewers would too! Haha heck yeah, your bike will get louder! 😁 Enjoy!

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.

Thank you brotherman! I appreciate the vote of confidence. :-)

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.

Thank you, Dakotaa Bookk! I'm glad you enjoyed the video! :-)

Thank you for the kind words, my friend. I'm glad you liked the video!

I'm really glad you liked it, my friend. Thanks for the compliment!

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.

Thank you Mohamed Kholif! :-)

Good feedback, thank you!

You're welcome, Simon! Thanks for stopping by.

Thank you, Darren!

Thank you, friend!

My pleasure, Marc. I'm glad you enjoyed the video!

Ok, thank you for the heads-up! I'll lower my music volume levels from now on.

@@FriedPi-mc5yt haha love it!

@@dani.0605 I can't recommend doing anything illegal, so check with your local laws to make sure something like that is legal first. If you're ok doing that, then yes it will free up some more power. Just don't forget to also get your bike tuned for the mods you have and you should be good! 👍

@@FaerodynMoto I ask is that good for my bike notting else. I dont wonna mods i didnt instal that only slip exhoust i now i wonna decat my so is that good for read safe for my bike?

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! :-)

Haha nice bike bro! :-D

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.

That's where the restrictive stock emissions parts really rob you: at higher rpms. Let us know how your project turns out, Jasper!

Lol ok, my bad. I'll be more mindful of my volume levels in future videos! :-)

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.

Haha yeah- I'm not sure if it's a real song or if Yammie Noob made it himself, but I found it on RU-vid channel CodeBlack07. Do a search for the video name "Yammie Noobs Bike Build Series Intro Song (looped)"

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.

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.

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. :-)

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.

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

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! :-)

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.

I can help you with the big words if they're giving you trouble.

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. :-)

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.

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!

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

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!

@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: findanyanswer.com/what-would-make-your-exhaust-glow-red www.cycleinsider.com/Aprilia-Scooters-Motorcycle-Reviews?type=Scooters&manu=Aprilia www.apriliaforum.com/forums/showthread.php?357858-Exhaust-pipe-glowing-red

@@FaerodynMoto thank you very much

@@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, RU-vid, and Rumble at the moment.

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.

They really have improved air quality!

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

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. :-)

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! :-)

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.

Thank you!

Lol you ok bud?

Right? 👍
