  1. 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!!

  2. This probably is the most calming, entertaining and in depth series about this topic, really great stuff, totally digging it, mate!

  3. 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.

  4. That segment at the beginning showing the various sources of road noise was understated but absolutely inspired, nice work

  5. How often do you guys release new content on your site? Loving the content so far can't wait for more. Thanks guys!

  6. Terrible montage of the video. It should be 7-10 min long. Cut off unnecessary parts and increase speed of everything else.

  7. So glad to have found your channel, it is excellent 👍👍
    Also companies should reach out to you for their marketing campaign, you have a good looking face for representing Luxury automakers like Bentley and Aston Martin 👍👍

  8. another great video mate, love watching you and the knowledge i get to learn from, look forward to watching more, great stuff

  9. For people watching on YouTube, 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.

  10. Thanks a lot brother for giving us the most precious video ever on YouTube 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…😉😉😉

  11. So the Guerrilla exhaust muffler in Holland will be out of business soon?
    Because they produce a flap controlled muffler. Tooooo bad I was gonna
    buy one very soon for my upgrades 😭😭😭😭😭

  12. silencers by Hiram Percy Maxim, son of Sir Hiram Maxim, inventer of the machine gun

    on the history of mufflers, the first car mufflers were designed by Hiram Percy Maxim (son of Sir Hiram Maxim, inventor of the machine gun) in around 1909 in the US, as before that cars didn't come with mufflers, and with the turn of the century, cars gained rapidly in popularity and the noise became a problem (the Ford model T debuted in 1908), these mufflers shared the same designs as firearms silencers as the latter were simply sized down

  13. "Explosion" is an incorrect term. These are internal combustion engines, not internal explosion engines. An "explosion" denotes a violent, uncontrolled release of energy were, in an engine, the combustion process is precisely timed and controlled, especially in modern engines.

  14. fantastic video, great quality content and editing! makes you wonder if aftermarket exhaust systems are even worth their prices, no chance they put in the same amount of R&D as OEM…

  15. 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.

  16. The EVs are going to bankrupt the muffler makers unless they can come up with some exhaust sound softwares through loud speakers.

  17. In regards to the water vapors, if temperature is such an important part of the longevity of the muffler, why wouldn't manufacturers include heaters to make the muffler reach that boiling point faster?

  18. Good thing about corded grinders is that you can keep the key taped to the cable so you don't lose it 😉
    Great video/series btw

  19. What I don't understand is cool car noise is regulated, so are planes, but why the hell are motor bikes not? They are so damn loud! I mean you get 2 types of people, motorbike riders and everyone else that hate motor bike riders. I know they are governed but they're not governed to the same noise level as cars. Why?

  20. on my car(chrysler300c 5.7) is muffler -suitcase and resonators on the end, -what is difference between and is important what is first in exhaust system

  21. That’s a good point. Try to drive your car more then just 10 minutes cause that’s not enough time for everything to get nice and warm. Probably why you see a lot of mufflers rust out.

  22. I keep all of my angle grinder accessories and tools in a box along with my angle grinder. But yeah one for each attachment is the way to go like AvE he has a wall of them all ready to go with various things mounted in them so you never have to mess with it.

  23. 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.

  24. Not only is muffler reducing sound levels, but also minimise, smooth out mechanical harmonics “vibration” from exhaust gas pulses.

  25. Excellent treatment of the subject but exhaust noise is not from “thousands of explosions”; gasoline burns so quickly, you might think it’s the same as a explosion, but what really happens is extremely rapid burning, with a flame front expanding through the combustion chamber in a controlled way. An explosion occurs when the entire fuel air mixture detonates everywhere in the combustion chamber and cause major damage.

  26. Sound waves actually are influenced by air movement. Sound waves are vibrations that travel through air as a medium, and could be lost in the wind if the wind is pushed away by a powerful fan or something

  27. Yo I just discovered this channel. It looks nice and high quality. Good job. Subing instantly coz I'm a gear head. Thanks for the content.

  28. If a large portion of exhaust noise is caused by expanding gases; wouldn't it be practical to use a multiple stage turbine, to slow the expanding gas into a progressively larger pipe; Then direct that extra power back to the crankshaft; or use it power axillary devices such as a redundant alternator and hydraulic pump?

  29. this show acts like a migraine commercial sowing all the sounds its fantastic! great videographical and analytical prospective.

  30. So, … a typical back yard mechanics attitude to preperation, ….. NONE !?
    Where's this, … where's that, … what the fuck did I do with the locking nut, …. oh, .. it's on my shoulders.
    Water vapour also comes in from the atmosphere, & obviously more on rainy days, which also add to the corrosive effect inside the silencers.

  31. OMG I was delighted when the grinder's hub lock wrench was lost. I suddenly feel so much less inadequate. Trust me, I know this pain well.

  32. hello, i'm a paying customer of yours who happens to also be an engineer of sorts (of the software variety, if you're curious). since i can't comment on your closed course content, i'm leaving my feedback here regarding the MAF video. first, i really liked the video but wanted to give you some info i think you will find interesting. the MAF is a hot wire anemometer. the grid arrangement in front of the MAF is actually meant to force laminar flow at the point of the hot wire so that turbulence does not cause a misreading of the volume of air. this is also why the direction of flow matters, if the wire were in front of the grid it would have no effect.
