Hello mr maisteer. I was wondering, everyone always says how an 8 to 1 or 12 to 1 or whatever to 1 is the best way to sound good. But you have talked about how the collector creates a change in area and a sudden change in pressure and therefore a scavenging pressure wave back to the cylinder. If im not wrong this is pretty much how the step in the primary works. So would it be better to have a 12 to 6 to 3 to 1 or a 8 to 4 to 2 to 1 to create more pressure waves like the step? Would multiple steps make the tone more "harmonious" how does the size of the step affect the sound... These videos are great. I come hoping for answers and just end up with more questions ❤

Best question ever. I think nobody really understood that concept until now. I think most still don't. Stepped headers are nothing new. I've read in Graham Bell's book "Four-stroke Performance Tuning" (page 288) about stepped headers almost 20 years ago - he described how big they should be and where to place them - for power. In Honda's "Technical Review 2009 - F1 Special" - they also mention the benefits of stepped headers: "At 17500 rpm, a gain of 4 - 8 kW was realized as compared to an exhaust without steps." They are not shy explaining the power benefits of stepped headers. But in no book or paper did I ever read : "Oh, by the way - stepped headers really change the sound." - engineers just don't care, and nobody else did seem to notice. Without understanding that - it's impossible to come up with a logical theory that could explain the sound of cars like the Zonda and the "all-into-1" headers at the same time. They seemingly have not much in common. On top of that, the "all-into-one" headers seemed to be a bit of a hit and a miss if they get to sound like that. It was also a bit of a stretch to come up with an explanation why F1 cars did sound the way they did. That the rpm is the "main reason" sounds logical at first, but when you hear that a V8 powered F1 car from before 1998 revving to 14,000rpm doesn't "scream" at all, while a later V8 powered F1 car at low rpm casually rolling by sounds way more savage - the rpm explanation becomes very questionable. "So would it be better to have a 12-to-6-to-3-to-1 or a 8-to-4-to-2-to-1 to create more pressure waves like the step?" - The next logical questions I have are: What happens when you combine these headers with the steps? How will more steps influence the sound? How big should the steps be? What role does the pipe length in between the steps/collectors play? (From my observation this seems to be critical - but not in the way I expected. It's more like: it works or not - without much nuance - like a on/off switch). But I can't answer them yet. That's what I need the support from "maisteers-exhaust-sound-resear.ch" for. So maybe next time I can...

They use stepped headers on motorcycles with V twin facing the road. One cylinder having a longer pipe than the other ,so to keep equal exhaust pulse travel time,the step up on cylinder pipe,so gases take longer to travel this bigger pipe,and both cylinders have equal duration exhaust pulses. Generally you step up piping on bends,so the gases gain pressure and reduce speed,so travel easier in bends.

I've got stepped headers on my engine and they sound great. It's a four cylinder and non-sequential collector so doesn't have that F1 spund but it definitely sounds special compared to a normal one. The steps also help extract exhaus gasses quicker and properly tuned length, means you get a greater scavenging effect at whatever RPM you tune them for.

Mr Maisteer… MUSIC we need to tune each runner to make a note, each runner a separate note of a chord, and we place them in order of MUSIC. We could play our song of engines… chatgpt says: Yes, it's possible to design the sections of an exhaust runner to have resonant frequencies corresponding to musical notes, and to arrange these sections so that their combined effect produces a chord. Here’s a step-by-step approach to achieve this: 1. **Determine the Starting Frequency**: Calculate the resonant frequency of the initial section of the exhaust runner. The fundamental frequency of a pipe is determined by its length, diameter, and the speed of sound in the medium (exhaust gases). 2. **Select the Notes**: Choose the musical notes that correspond to the desired chord. For example, a simple major chord consists of the root note, a major third, and a perfect fifth. 3. **Calculate the Required Frequencies**: Convert the chosen musical notes into their corresponding frequencies in Hertz (Hz). For example, if you choose an A major chord: - A4 (root) = 440 Hz - C#5 (major third) = 554.37 Hz - E5 (perfect fifth) = 659.25 Hz 4. **Design the Sections**: Adjust the length of each section to achieve the desired resonant frequencies. The formula for the fundamental frequency of an open pipe is: \[ f = \frac{v}{2L} \] where \( f \) is the frequency, \( v \) is the speed of sound in the exhaust gases, and \( L \) is the length of the pipe. - For the first section, calculate its length \( L_1 \) to achieve the root note. - For the second section, which is stepped up in diameter, calculate its length \( L_2 \) to achieve the major third. The change in diameter will affect the speed of sound and the resonant frequency, so adjust \( L_2 \) accordingly. - For the third section, calculate its length \( L_3 \) to achieve the perfect fifth, considering the new diameter. 5. **Adjust for Diameter Changes**: When the diameter changes, the effective length of the pipe changes due to changes in the speed of sound and the acoustic properties. Use appropriate corrections to adjust the lengths. ### Example Calculation: 1. **Initial Section (1.625 inches ID)**: - Assume speed of sound in exhaust gases \( v \approx 350 \, m/s \). - For \( A4 = 440 \, Hz \): \[ L_1 = \frac{v}{2f} = \frac{350}{2 \times 440} \approx 0.3977 \, m \] 2. **Second Section (1.75 inches ID)**: - Calculate the new speed of sound for the larger diameter. - Adjust the length \( L_2 \) for \( C#5 = 554.37 \, Hz \). 3. **Third Section (1.875 inches ID)**: - Similarly, adjust \( L_3 \) for \( E5 = 659.25 \, Hz \). ### Final Considerations: - The exact speed of sound in the exhaust gases can vary based on temperature and pressure, so these need to be factored in. - The step-up transitions will affect the exact resonant frequencies, so fine-tuning and empirical testing might be necessary. By carefully calculating and adjusting the lengths of each section, you can create an exhaust runner with resonant frequencies corresponding to a musical chord. This approach combines principles of acoustics and exhaust dynamics to achieve the desired sound profile.

a few years back I did a V10 F1 header copy design in Grabcad complete with stepped headers. just grabbed a picture off the internet and put it into CAD using a lot of creativity. I read somewhere why they were stepped but forgot why now. a few days back I attended the F1 exhibit in Toronto and both Haas (Ferrari) and Mercedes engines were featured. Of course they are turbo V6 engines so entirely different from days past. As they both had heat shielding on the primaries it was hard to tell on any detail construction.

F1 engines just like diesel engines are very efficient - they send very little energy out of the exhaust. I don't see how splitting up weak pressure wave into even weaker pressure waves can result in a greater sound than what we know already. The engines I'm curious to hear with stepped headers are the rotaries. They send A LOT of energy out of the exhaust. They might set a new standard.

Changing the diameter of the pipe changes its characteristic impedance, and yes you get reflections as a result. This was all well studied for radio and radar, and any transmission line or transmitter. Think of the exhaust pipe termination (outlet) being like a radio antenna and you're getting close to how a megaphone works. If you could hook up an acoustic equivalent to a SWR meter, you could in effect "impedance match" the engine speed to the exhaust!

5:36 I see one distinct step on the '98 header per primary. Presumably that's sufficient? The implication seems to be that more steps will get you a higher frequency. It looks like it doesn't need to be particularly large step. I think my two main questions are: 1) Is it okay if it necks back down to the original size? 1.5) Does it need to gradually neck down? 2) Does it need to be a sharp step? Bonus question, does the location on the length of the pipe matter? I would assume one step per primary might be 4x more effective than a step after the collector? ...Also it seems to me that it's likely 8:1 is nearly irrelevant. Seems like it has been conclusively proven that it's not a cheat code at all.

You are actually the coolest guy on the internet! Thank you for sharing the amazing secrets you have discovered! I have one question, what are your thoughts on Anti-Reversion Chambers in the exhaust?

Guten Tag maisteer. I think I believe if you ever need to figure where to put the Steps and how much I think you should consider the Complexity of Cam timing as well as how I believe and I know!!! That nascar and formula are 5th stroke engines due to the fact these engines are Exhaust driven. Your second video briefly explained how pressure goes back and pushes back residual exhaust out of the cylinder. But doesn't fully explain why! The answer is Simple a tuned exhaust when the piston close to if not at TBC. (most would assume no flow would happen) But that's totally wrong!! The scavenging effect from the near opening of intake and the near closing of the exhaust valve (overlap) is so strong it brings in more air than the piston going down in the intake stroke. That's the 5 stroke and how pressure waves can also Benefit this effect. Now for the steps in the headers. I believe that you could measure pressure waves with a pressure Transducer. You can probably measure how long the reflection wave takes from one end to the other as well as making tests and whatever. This information is from -David vizard (How to build Horsepower) I consider you read his book and etc. hope this may give you a hint or a clue where to go from here. And I do hope this gets to you. As of right now I'm still reading and learning from David vizard so thank you if you do end up receiving this comment (as a token of gratitude here's a close to nascar engine with stepped headers 297CI SBC revving to 10K rpm ( kzitem.info/news/bejne/0mZo0IGQsoF2dqAsi=u2py0SCkPok1njXx ) . Thank you

Do you think that using an individual pipe for each exhaust valve would change the sound? Peugeot did that in the 80s with the 405 mi16, as a 16v 4 cylinder had 8 exhaust header primaries merging into one 8-1 collector.

Oh my!!! 10years ago i would have had the best f sounding r6 in the world with this knowledge 😂 anyways with an aftermarket header (leovince) the sound was not bad at all (btw i notice the header was loose stacked and held in place with springs… (!!!)

4:58 Please someone explain it to me. First i tought that he is only showing weldings but there are points where two different size pipes are welded right? Starts with smaller pipe then goest into bigger pipe, that is second secret?

Then what if you put a shit lot of steps on the header ? It could sound even cooler or bad idk 😂

2:41 this actually sounds a lot like Lister Storm GT1 and the later Aston Martin DBRS9 GT3 race cars, both from the front and from the back.

I wonder if this would help a 6 cylinder get a higher pitched note? I want to put a 3.2 m104 in my w124 and would love to try headers like this in the hope to get a high pitched sound

The principle should work on every combustion engine. But the results will widely vary.

There seems to be a wide variety of pipe lengths that work, and some that simply don't. In my mind it I was expecting it to NOT work most of the time, but it does - so this is clearly something I don't understand yet.

The exhaust might be too short depending on what bike u have but if u want you could give it a shot
