This episode has everything you need to know about the exhaust muffler, or in British English, the silencer. We cover what it does, why it's needed, and then chop a muffler up and see what's inside. I also talk about exhaust back pressure and the differences between turbo muffler, absorption or straight-through mufflers, and finally we look at chambered designs.

You guys literally started at nothing and have a solid foundation for a great channel. I'm glad to have been a part of your journey fellas.
Absolutely love to watch this channel
Mobius 1 same I bought his course it’s great
Who much does it cost the course?
Aninullah Faizy it was 25 so worth it
Aninullah Faizy $25
That segment at the beginning showing the various sources of road noise was understated but absolutely inspired, nice work

My god the production quality is so good.
The best educational automotive channel I've ever seen.
Never thought of a muffler as a kind of a musical instrument before. Brilliant!
17:30 It's called a turbo muffler because the first production example of the muffler design was used on the 1965 Chevrolet Corvair Corsa Turbo.
Nice one! The amount of knowledge you guys have is terrific!
I thought the turbo muffler is just a mod to the standard baffled muffler designed to improve airflow and (completely by accident) and to not cut the sound of turbine so much. Guess I was wrong.
@@howacarworks There's a lot of things people sell as "turbo" mufflers, but it'd seem like that phrase is used more for non chambered fiberglass packed straight through or multi pass mufflers. You kept calling the chambered muffler a turbo muffler and it was kinda confusing. To me the resonator you have is more of a "turbo muffler" than that thing.
@@TheBreaded I knocked out my cat conv. I think some got in my muffler. I wonder if ill be able to clean it out
@@TheBreaded Maybe ill try it. I have it unhooked now.. I just don't think compressed air is going to blow it out. It has too many turns.
I just found this channel randomly and I have to say I am impressed with the detail and everything that goes into the video
For people watching on UA-cam, I'd definitely recommend checking out the website and the full video series. I've been binge-watching them and they're massively helpful and well done.

Hello there,
Your videos has no sound on your website, unless you use a head phone or hands free speakers,
Just to let you know
You should add quality settings in the app for videos, like 360p, 480p etc.
Hi how a car works
I just wanna know when will you upload about fuel, ignition, transmission, differential and brake?
I didn't see them on your website and it made me keep waiting to apply your courses.
Watched this video, I am a complete amateur with a love for cars and with a thirst to learn all I can about them. Found your videos and i have been blown away by your knowledge, explanations, the production quality and the humour. Keep up the amazing work mate, the best 20quid I've spent. Totally recommend.
That was absolutely superb. So much knowledge and so good at imparting that knowledge. Also, great camera work and great sound quality. The film created showing the different noises in a car was absolutely brilliant.
cant get enough of your videos.
just muffing terrific
Criminally underrated. Superb quality and the topics are eloquently discussed. I'm glad I found this channel.
If anyone is wondering his program is very much worth it. He explains everything in great detail while making it very simple to understand. I always zone out watching his videos for hours and I step away feeling like my brain just got bombed with knowledge.
These are some of the best videos I've seen on UA-cam full stop. Thank you for this fantastic production!
I absolutely LOVE this series. Seriously cannot wait for more and more videos.
Where do I watch more
Well spoken, well presented. Clear and concise. This is how it should be done!! You guys deserve all the praise.
Legit watched 4:23 minutes and I went and bought this and I've been binge watching this
Superb explanation
Most people will learn FAR more than they ever wanted to know here! An OUTSTANDING start to finish explanation. I retired from a company that manufactures the exhaust systems for one of THE major auto manufacturers in the world.
You guys have begun to put together a brilliant series!!
Video editing is amazing, I can imagine the amount of work put behind editing, great videos
Just bought the course! I'm so excited about it!
Keep on with the great work!
Wow! Stuning! Love your stuff mate. More people are gonna see this.

I've just discover your channel, and wow, you guys deserve millions & millions views. Thank's for that quality
Thank you from France :)
Iam an automobile engineering student and moreover an automobile enthusiast, was searching for informational videos ...finally i got ds..n nw iam totaly addicted to ur channel...
Super video. Very detailed and depth of knowledge. I never new the engineering behind the silencer until I watched this video. The sound effects at the initial of this video was too good. Thank you Sir.
I never thought that I will enjoy so much learning about cars. Guys, buy his courses and support him it's really valuable even I would say it's too cheap. Just Amazing teacher!
Thanks a lot brother for giving us the most precious video ever on UA-cam specially you don't irritates us by too much Ads..I wish you will hit 1M sub as soon as possible... Lots of love and respect from INDIA...😉😉😉
This probably is the most calming, entertaining and in depth series about this topic, really great stuff, totally digging it, mate!
I really don't understand why people waste their time watching reality tv, when you have entertaining content like this 👍
@@allamasadi7970 Because some settle for sitting their asses on the couch and munch popcorn brainlessly. Others are willing to learn :)
I like this guy. hes super smart, funny, and gets distracted just like me.
Jesus, these vids should be shown in schools. This is wonderful!
Love your videos!
You mentioned the Rotary engine, nice.
This is really interesting material. I appreciate the effort you put into providing it. Many thanks!
I love how you include all the niggling troubles you experience with the angle grinder. Felt really like "you're just another bloke like us", much authenticity there 👍
EDIT: Love the whole video! Serious knowledge + some levity / light funny moments, but not overdone. You've won yourself a subscriber!
Wish this series was for free, the production quality on this is amazing
Brilliant and very comprehensive tutorial, many thanks.
Can’t get enough of these videos
Your videos are incredible. So much effort has blended into those videos. Keep those coming ♥️

Thank you for your thorough explanation! I got from thinking that the muffler was nothing but a hollow tube to knowing the ingenuity that goes on inside of it.
Great work! Please continue with this type of content. Very usefull.
this channel is fantastic and the video series is well worth it! Honest to God I'm glad I paid $20 for the entire series and no longer have to watch ads. Well worth the money!
Liam when u paid the 20, did u get access to more videos than the amount of videos they have posted on their UA-cam channel?
Very informative! I really appreciate your good work! Please keep it up👌👍

Free Idea !! - First touch of that grinder on the metal surface with Sparks flying - in super slow mo for like 5 seconds, and with the music ( like when you're were goin up that ladder). Pure epicness.
Also, you could get ready with your gloves and masks in style , like they get ready in the superhero movies , (with some epic music) lol
Excellent explanation with pratical presentation.....👍

Awesome video!
I love this channel....from India 🇮🇳 kerala 🌴🌴🌴
Really cool video. Like your presentation. Professional but human. I've subscribed.
Awesome channel. Congrats!!!!
I think your videos are absolutely spot on and agree that these should set the standard for the next 10 years. I was very close to buying the full series but unfortunately I’m not convinced I’ll pick up anything highly beneficial for an intermediate DIY mechanic. I would definitely be bought in however if there were videos covering diagnostics (e.g. PWM, fuel trims, ignition timing, voltage drop testing, CAN bus/MOST/LIN networks, control module anaysis, etc.) and not so much focus on how things work. Certainly knowing this helps one infer how to fix things diagnostically but it’s not the complete picture. For beginners however I think the video course would be useful. I hope you add some advanced courses soon!!
It's designed for beginners :)
Best Video on how muffler works. SEVEN STARS *******. Thanks from the land down under. AUSTRALIA
amazing guys. keep it up
God bless U Buddy, so educated so simple explained. 👍👍👍
