- On paper, the idea looked great! Building the first Mercedes 12 into 1 headers to make this M120 V12 sound like a F1 racecar, or at least like a Pagani Zonda. Absolutely not keyword related mentions: Donut Media and effspot insane $12,000 exhaust, nor Brilliant exhaust S600 orJP Performance 500E V12.

What song is playing at 26:50? It sounds so serene
i was stupid... now im smarterer
i never really understood how wind instruments work or what parameters decide the frequency it'll produce despite watching videos on exactly that question,now tho after a vid focusing on a bad sounding V12 i 100% do.
Ur not stupid . I know some great mechanic who do amazing engine work and they don't even know how an engine work .
The writing is great and the editing is hilarious. Your explanations are engaging and I'm really excited to see what comes next. Thank you for your hard work!
I suppose a sense of humour helps a lot when you are trying and constantly failing to achieve your objective!
I admire the determination.
Thank you very much for watching... hope there can be a next one soon.
@@gregculverwell Certainly.... I'm failing my way to success ^_^
@@maisteer
That's the way real life works.
Yeah, failing can be fun ^_^'
it really is a dark art. i remember a hotrod channel was showing the dyno results of hammering a big dent into one of the header tubes to get it to clear the brake booster. it gained them like 20hp on a chevy small block
I knew I got more horsepower after ripping off my front bumper

You're a blessing to the car community. Your live examples aswell as sound comparisons beat every theoretical teaching and explanation for everyone getting into cars.
The editing is crazy. This video deserves far more views than it has.
If you tell your friends it will...and thanks for watching ^_^
How bout you edit the word misstake, only seconds into clip and there's a mistake.

The first 12-into-1 header video took 232 days to get to 1 million views, since this is 4-times better, I would say 2 million views in 116 days should be possible... ^_^
In addition to my other comment, here's an alternative way to make 12-1 headers: th-cam.com/video/UDXV2XmKhzw/w-d-xo.html&ab_channel=stainlessheaders
No one cares
Große Erwartungen. Ich drück die Daumen.
Yeah ^_^
@@maisteer i care
I love this. Engineering is hard. Automotive engineering is even harder. Automotive fluid dynamics is a dark art. TH-cam could use more examples of showing the often underwhelming results of trying new things and the iterative and often painstaking process of improvement. So refreshing compared to cookie cutter projects that everyone pretends to be amazing and makes everything seem so easy or black and white.
This channel is seriously one of the best channels ever made. Never stop sharing with us. The blend of knowledge and nonsense is an art.
The twin motorcycle engine test bed is better than anything I’ll ever build in my life.
Brilliantly made, thanks for the effort! Lovely to hear that V12 sing.
Hi Octav... glad you found the new video already. How was your drift season. Did the turbo V12 hold up?
@@maisteer Hey hey, don't underestimate my commitment, I actually managed to catch it Premiere. You really outdid yourself with this one.
On my side, the S14 V12 Turbo build was constantly delayed every race by various factors human factors. Rollcage guy a few months, wiring guy etc. So I never got drive it yet, quite annoying.
In an awesome turn of events, though, the first S13 V12 Turbo built here by one of our top tuners 11 years ago became available for sale. I wanted her since I first saw her so I worked out a deal and bought her at the final round. Makes 600whp 800wnm at 0.8 bar and 700/900 at 1 bar, internally stock M73B54.
So I did get to drive a V12 Turbo Silvia, albeit only a few laps because I managed to put it into the wall slightly in quali. We suspect a number of technic issues led to that and while it looks dramatic, the damage was rather limited and fixed overnight. I have a video of the lap and crash on my channel if you want to check it out.
There's a lot to say, might come back with detailed feedback but in short:
Godly powerband, powertrain feels invinciple, I like the noise but it's mostly screaming big turbo, not V12, lighter than you'd think (1240kg 57/43) but still very front heavy and polar inertia is heavily affected. Having what is likely the biggest turbo in the paddock in front of a V12 makes it feel what I imagine a V16 feels like :) I also found it harder to "grab" the ground in search for grip compared to a smaller engine with less inertia and instant torque. Can drive around that, of course, but it is a characteristic.
But it's unfair to judge the car only after 5 laps and before I get to put a good setup and geometry on it. It has tons of potential we hope to unleash next year.
I'll be using it as my backup car but main it while the S14 is built to DMEC standards and get a different powertrain in it, no rushing. S13 scratches my V12 itch and feels like a great reliable practice car but the laggy polar inertia doesn't fit my style at all so will be moving away from V12 on the S14. Likely 2JGTE which is still heavy and long but fits the bill in other ways.
Long rant, sorry, but that's why it took so long to reply, had to find a window.
I hope everything will work out in the end and that you can get the 2jz done without as many problems as the V12. Wish you a succesful offseason then and keep me posted.
And that crash looked quite violent from the drone ^_^
@@maisteer Thanks a lot for you kind words, it'll be a fun offseason! It wasn't exactly a light crash but the damage was minimal, considering. I was fine, only things that hurt were my right knee and my ego :)
Hopefully the knee and the ego will be back to normal soon. ^_^
I love how this guy exudes enthusiasm for the subject while ironically presenting the information in such a calm and underwhelming demeanor that it is actually funny and entertaining.
I LOVED the way you explained your first toughts and ideas, how you documented the explanations, experiments and failures, the corrections... Amazing video. Mechanical engineering student here. Greetings from Argentina
At this point you could try to detach the headers from the engine, place a little speaker at each exhaust inlet (one at a time) and a microphone at the collector and do a loopback sine sweep measurement with REW (roomeqwizard) to check if all runners actually have the same acoustic frequency response and more importantly time delay. I believe the high pitched sound can only build up if the pulses are timed exactly right, like down to a few 100 microseconds or maybe even less idk.
It's like with some synthesizers, where you have 2 sawtooth oscillators (D50 for example). If you delay one by exactly 180° the sound is one octave up. delay it slightly less or more and the lower octave comes back immediately.
Just my uneducated guess though. Anyway keep up the good work and great content!!
yes, that can be true. Can be its on the fidelity of the built. I know that,😂 couse HF=high fidelity. I testet that issue with my Model D and SH101 on the roof of my Lancia. It worked perfect! ✌
I didn't understand the loopback part fully yet from reading it, but I will look into it. I think I understand the concept of what you're trying to say and it sounds like a plausible and really good idea to check.
Just as a note tough. The timing has to be spot on and that depends on the distance AND speed. And if we have different temperatures and/or pressures the pulse speed will be different between cylinders and then the timing will be off too, despite being equal distance. But just as a side note. There many things to get right at the same time, I believe.
@@maisteer Seems like my comment got auto-deleted. maybe because of the link?
@corri303 Yeah, links get auto-deleted. I can't even see them.
This would possibly be a great way to measure "exhaust frequency response". Never crossed my mind. But the speaker should have a proper air-tight adapter to fit the header inlet. Maybe also a closed enclosure. I'd probably use something like a 4-5" high power wide range speaker. In a perfect system one would have ten speakers behind a 10 channel DSP that is able to adjust delay in very small increments. That could be used to tune the header lengths. And measuring could be done one at a time or just as many as one wants. One could also make holes for additional mics, to measure the response in different parts of the system, though it could have little to no use, depending how the sound waves behave inside.
I would really like to see someone try to test how the response curves from this kind of measurements would relate to actual output.
I can imagine a way to sweep the actual engine and making a corresponding 3D graph of the exhaust frequency response. Think of a response graph, but add them one after another like one per 10-100rpm and show it a bit like a 3D fuel map.
So excited to be watching this! You're doing stuff I've always been interested in, but never motivated enough to do the work. :)
Me neither.... so I got my friend Tim to help ^_^
@@maisteer Such a great thing to have a Tim!!
cute dog i like his smile...@@tptrsn
@@user-ye9py7ff1j Thank you, he was the BEST boy! :)
Everybody should have a Tim ^_^
This felt like a fever dream to watch but I loved it. Exhaust tuning is such a mystery, it's so cool to watch this journey!
Man, the editing and engineering effort in this vid is astounding, and the subject is something that I've been interested in as well. I've always wondered how the 2018 Porsche rsr often sounds like more than one car when it accelerates, and this vid might've indirectly answered that question with your explanation on pressure waves
I've been waiting for my entire life for exactly this content. The academic approach, the willingness and ability to test, the proper taste in exhaust note, and the journey all make this my favorite YT channel now. Keep it up.
Thanks. No academic here tough ^_^
But if you could tell your friends about the channel too, that would help a lot to keep making content faster ^_^
Simpletons may try to find other solutions, but the modeling has already been done... There are no secrets to it... you will never understand that trial and error engineering left us when computer modelling arrived...it just did!
I think gma should hire this man to make their engine sound even better
Yeah, do you have Gordon's number? ^_^'
This was amazing from start to finish. I love your style.
Great work, both in how the video is put together and the breaking down of the engineering behind what you're showing.
Thanks for continuing this and being straight up about the 12 to 1 failing in the beginning! I’m loving all of the videos you’ve made on exhausts man.
I remember thinking at the beginning of the video “That sounds a lot like six”.
Hilariously performed, fine sir.
Been waiting for your video for such a long time glad it's another masterpiece! Keep going!
How have i never ran across your channel your editing skill are off the charts good! I'm really impressed gonna binge the rest of your content!
Recently Tim's car was featured on Reddit's /r/drifting sub and unfortunately most folks didn't like the sound either. I'm glad it's being sorted out and I'm also glad having found this channel. I wasn't aware that some serious math is being involved here to get it right. Keep it going!
Can't blame the reddit people. Much worse were the people telling me that it sounds good at the event ^_^
This is incredible. Please continue this amazing series with your excellent editing as well.
This is now my favourite channel, can’t wait to see where you go with this!
This is brilliant I wish you all the best and hope we get to see more in the future.
cool stuff man, would love to see more- sending some support
Thank you very much for your support... But I need to to warn you! I'm gonna waste that money on exhaust piping ^_^
@@maisteerthat's what I'm here for!
@@maisteerain't that the point ?
You deserve way more subscribers. Keep up the great content, and I look forward to your next update in this saga.
Thanks Cavedog, if you want to shorten the time it takes to make the next video, you could tell your friends about this one. I'm sure they will like it too.
Nah make the video as long as you need ain’t no one in a rush to catch a plane
please continue making videos these are briliant.
Incredible video!! This is one of the best I’ve seen!!!
To the top of youtube you go. Great info, great editing, nice style.
The pressure wave vs exhaust gas segment was nothing short of genius. You'd get full class participation if we taught school like this.
Why schools don't teach like that then? Don't they care about full class participation? ^_^
So I've got a V12 car sitting on my farm and I've been wanting to do unspeakable things to the exhaust system, but didn't really know where to start. I'm absolutely glued to this series now.
Soooo much time and effort went into this video and I fully appreciate every second of it!!!!
Only with testing, research and effort you can achieve your goal to make the V12 sound and screan smooth like heaven.. im really hoping you would fine what it needs to make that happend. I'm so exiting to see what the next video will show, keep up your work dude! I appreciate all u did to this point
Thank you Matias. Hope you tell your friends how much liked it, then it might not take so long to make the next one. Have a great day btw.
Like the last video, quality content! I wanna see your next one so here’s a tenner to achieve the goal!
I also had mixed results with my m70 6-1 and x pipe. Your last video helped a lot! The tone was only really good without any sound deadening at all. So Working on a solution to that now!
Thank you. But be warned I'm gonna waste all that money on pipes ^_^
Hope you can get M70 to sound right, tough. And I hope i can figure that out too by the next video ^_^'
Great vid man humor is fresh
keep plowing its gonna be a simphony
love your video your accent is not a problem and your English is good, love how much you went in depth to explain exhaust sound and waves.and the editing is nuts
I just love the content and your editing style. Very fun to watch and can't wait to see what happens next.
Me neither.... and I don't want to wait again to make another video... If you would tell your friends about the video, that could really shorten the time it takes to make it.. But thanks for watching Austin
Beautiful work. What an amazing sound quality difference between steel and titanium, I never considered that!
This video is beyond amazing ! The editing is superb, the visualization of the firing order is on point, and has crazy amounts of knowledge in it ! And the first time i am seeing someone reference Bell's great books
Best ever explanation of exhaust that I have ever heard, and best understanding of exhaust I ever have came across, excellently explained
I admire your extensive work to get your desired results. It is and also will be, worth it. I've been smitten ever since I saw that Japanese video. The noise is intoxicating. All the best dude!
My God, how have I just now discovered your channel?!?! AMazing! Instantly subbed
It's less than a year old. You're still early ^_^
this video is amazing, love the editing style and animations! Adding music for the firing order was a genius idea
Great video, the editing is awesome! Would like see more content like these.
This is insanely good content, really nice editing skills and a kind of humor that i really enjoy, keep it up!
I will... just for you. And every friend of yours you will tell about this channel ^_^
Must be frustrating to not have the result you wanted yet, after all that hard work.
However this is why it's called "tuning" and not "Randomly slap Ebay parts onto your car".
Persistence is key! Great to see you are sticking with it.
Also did the V12 car ever get on the dyno?
I swear it sounds exactly how an engine does when you've got a fairly open exhaust but not enough ignition timing.
If you're running a conservative timing map to keep the motor "safe" then yeah it usually sounds gross, especially at low load.
Because the gas is still aggressively expanding at the time it's coming out of the exhaust pipe, rather than pushing the piston down.
So it sounds a bit more "chaotic" and loud out of the pipe.
It would be interesting to hold the motor at a set rpm and load and adjust ignition timing forward or back by say 10 degrees and see if you notice a change in sound quality.
"Also did the V12 car ever get on the dyno?" - not yet, Tim wanted to fix the throttle actuation before, as he noticed at the Iron Drift King they needed some improvement. I'm also curious what the tuning will do to the sound, and also how the power curve will look.
Tuning can’t change the overall sound. Porting head and camshaft design change the sound more.
@@Fk8td "Tuning can’t change the overall sound. " - not true
"Porting head and camshaft design change the sound more." - not wrong ^_^
did you watch the video at all?@@Fk8td
goddamn this made me giggle a few times.
Fantastic editing.
So low effort, yet so high effort at the same time, I LOVE IT.
this reminds me of late 90s early 2000s informational videos wed watch in science class... the right amount of information.. the right amount of funny and all the pop ins you could ask for to explain the information you could want! love it
This is the greatest exhaust video in the history of mankind and i did in fact only WATCH IT TO HEAR THE EXHUAST OF THE 12 IN 1 but man am i glad i stayed and watched the ENTIRE thing. Im an big fan of exhaust sound and acoustics and how it all works, spending hours reading on it this video combines it all with a humorous touch. Great video with so many great resources!
Keep posting videos brother! Awesome content.
it's been a while i havn't seen such a good editing, perhaps even the best
FUEL QUANTITY!!!!!! i ben down this road and i dont publish. the stuff i do , too busy, not on facebook nor instagram. but i can tell you, you're looking at pipe length, pipe sequence, diameter, cam duration and you have made NO MENTION ABOUT FUEL QUANTITY. fuel quantity is thee most important factor to sexy noise next to ignition timing and cam duration. my rig is similar to that old shelby on your last video. sounds the same, ok, mine sounds better and higher pitch but when i removed the 500cfm 4bbl holley for a 210cfm 80's 1bbl toyota corolla carburetor, the good sound went away and the redline dropped 2000rpm from 10,400rpm down to 8,500rpm. fuel increases pressure wave amplitude and pressure wave onset rate or gain or jerk force, whatever you wanna call it. i bet if you put bigger injectors like 32lb or 40lb and retarded your timing and changed nothing else, , that F1 v12 sound would come out of your rig. good luck.
Hmm make sense since f1 use Wet style fuel injector on top of the ITB. Pretty good idea
This is the best content on car exhaust sounds in all of TH-cam. But how strangely the sound is mixed, everything is fine in cheap headphones, but on the speakers the exhaust is very loud, and the voice is quiet!
insanely high level editing, good job
Great video! I hope you keep making more stuff like this.🏎🎶
I am currently doing my own 6-1 headers for a merc m120, this has been super helpfull. Thank you Maisteer, keep up the good work!

me neither.... ^_^
Amazing edit and amazing content! Great job! This is the 101 on how exhaust note is achieved.
This is a great video. Dude went hard on making the content engaging.
I am glad to finally see another person who knows about how cylinder groupings affect exhaust pitch. You’ve done an excellent job with the manifold, now please give Kreissieg a chance with the remainder of your exhaust system. They are the best that I have seen when it comes to the post-manifold work.
Tim did an excelllent job... I didn't. Or it would at least sound good ^_^
We gonna figure out the rest for sure.
Absolutely incredible content! There's been a lack of decent publicly available research onto what makes cars sound a certain way. I think most supercar companies only have a few guys that understand the theory but that is becoming a dying art in the age of efficiency and electrification. Finally it is community that'll crack the code.
No engineer I've ever spoken to, has had any clue how it's done. So I need better engineers to speak to, or find out myself ^_^
@@maisteer I'd say somehow find someone at Yamaha who worked on the Lexus LFA, somehow they made that thing sound so beautiful
@@isaiah9639 They have the advantage of being able to do trial and error. Theory and/or computer simulation only go so far. Say the topic of eliminating drone: sometimes it's as unsophisticated as measuring the frequency response and working out what the droning frequency of the exhaust is and putting on the quarter-wave tube or Helmholtz resonator to cancel that out (or changing the design to avoid that) -- as much it would be nice to predict it precisely on the simulation or by theory.
Anyway for what it's worth you can Google the Lexus LF-A exhaust design. It looks like it is a 5-1 collector with a pretty steep merge angle. It is true dual back to the rear muffler and the only crossover between the banks is inside the rear muffler somehow. It looks like the primaries are maybe 45mm (?) and it goes into either 60mm or 65mm.
Came for the noises, stayed for the memes
the edits are crazy
i needs more
This guy needs to start a university and teach literally every subject like this.
This epic quest for v12 purity is worthy of song :)
Amazing video brotha super dope💯 keep up the good work🍻
7:00 I was expecting this to transition into the piano in “Still D.R.E.” Would have been perfect!
I love your videos and have been waiting for them for a long time. Please make your voice a little louder in your editing software.
I will try to make the sound better everytime, but not only in the editing software ^_^
@@maisteer thanks so much for your reply and videos! I find them informative ｡◕‿◕｡

not even mentioning the music, screenshots of papers, animations, storytelling and jokes
Seriously amazing work and dedication. I stopped editing videos because it took a lot of time and mine were nowhere close to this complex. And this was funny on top of all that.
literally the best and informative content ive seen in a while
Very good video I look forward to your discoveries :)
I've been aching to learn more about this subject as I have fabricated a 4 to 1 header myself. It sounded ok, but it wasn't amazing. I should experiment some more...
@@Chris-cy3uq I'd argue that even with even firing sequence, the exhaust sound from factory can be improved upon greatly. Having said that, I see where you are coming from, but I will still play around and see where I can improve!
Wish your voice was a little louder than the rest of the video.
This is the first time that i have subbed to a channel after watching just one video. I love this style of editing and your humor💁♂
I never see a Crazy edit like that in a car vídeo before. Awesome.
Waiting for the next Episode.
Damn didn't realise you got so much hate. Please ignore all of it. The amount of work in the video is insane + this is a very interesting topic and I'm excited for the next parts
actually very informative video, in the start i just thought it sounds like an M70/M73 bmw v12, they just sound like a loud I6, but how in the hell did you not notice the power loss from only one bank of the v12 working?
This editing and work is on another level.. no on another planet. Absolute Great work.
This is the best video ive never inteded to watch 😂😂😂😂 great job with the editing and its just so informational u get stuck in it 🔥🙏🏾🤣
Man, I tried to watch the entire thing, but your audio mixing is as bad as your video editing is good. Please re-upload.
You’re overreacting.
I hope he takes this to heart because youre so horribly correct. The editing and information is great, but theres z e r o consistency in sound
@@Powersproductions130I know the commenter is wanting him to edit the audio when the whole point of the video is to compare the sound of exhausts to get it to sound better. What’s the point in comparing exhausts and making a video on it if you are just gonna edit the noise. Makes very little sense 🤣
some people may hate you for your accent and the way you present but that doesnt include me
keep going and you will soon find the perfect sound for that v12!
ps: i think youre the only guy who makes the only videos that i dont fast forward a few seconds because the writing is so good
Thanks for not forwarding them ^_^
@@maisteer
entered this video not knowing at all what to expect, came out a new subcriber with a lot more knowledge of exhaust/headers
I really appreciate that you're enough of a scientist (and I also appreciate that Tim is enough of s sport to pull the motor *yet again*) to swap back in the other merge collector after you realized the "dead bank" issue to see if that was actually the required piece of the puzzle.
Would be nice if your voice was slightly louder than video fragments!
Getting the audio right seems to be the hardest thing for me ever. Not only with the engines. ^_^'
I appreciate all the reaseach and effort.
this video was crazy good! great blend of humor, education, and cool cars! Nice editing
a lot of the sound effects make it hard to hear what you’re saying, you should increase your voice or lower the sound effects
This has been a trip and I can't wait to hear the rest of the story. Excellent.
Best TH-cam vid I’ve seen in a long time. Actual quality content… a unicorn in 2024 TH-cam. Entertaining and educational.
Great video! I had no idea how many factors come into play JUST from the exhaust system - things I never considered before that make a big difference.
Even better, you present it all in a way that is informative, easy to understand, AND doesn't get boring.
Liked, commented, subbed. You earned it.
holy shit this feels like a YTP that is not only hilarious, but also genuinely informative - instant sub
