      Thanks for offering these, looking forward to experimenting! Your website says both megaphone and megaphones (plural) in the description , so it's not clear to me if they come in pairs or a single megaphone when I try to buy, may want to say "single" or "pair" explicitly. Also, have you experimented with one on a turbo 5 cylinder like a TTRS 2.5T?

Equal length isnt the thing, its getting the exhaust pulses out at equal time and hopefully in equal velocity.

  • @danieldimitri6133
    @danieldimitri6133 หลายเดือนก่อน +8

    Just a few notes... The results you got are great 👍. As a muscle car guy I was afraid of it sounding like an open wheel indy/f1 being that it would have even firing banks and so many cylinders. This is actually better than what I was expecting. But if you wanted an exotic f1 sound or to harmonic tune the engine it would be easy without megaphones which the math of those seems to be a guarded secret. On 2 strokes they are often regarded as sound wave reflectors but when glossed over in automotive exhaust literature they talk about sound wave timings extensively but then some may say megaphones don't follow the same mathematical model and require testing. Not sure why that would be but darin Morgan who designs intake systems that also use sound wave reflections talks about angles as part of the rpm range so perhaps the reflections aren't a function of the average length to the cone and just happen when acoustic impedance sufficiently changes so I don't have enough acoustic knowledge to speak on that. But I do know how you would typically tune collector extensions and primary header pipes when megaphones are not involved. Sometimes the path to the best x or H pipe placement is blocked but because it's harmonic there may be subsequent locations down stream. These down stream locations may be lower in pitch so if an f1 type sound is desired you may need to pinch a harmonic (ask a guitar player about string harmonics) to make it high in pitch if you so wanted to. To do this you could add a stepped pipe or an H or x at a half or third or quarter point in the path getting to the tuned point. A typical location for a x would be around 33" behind the end of the primary header pipes for a 6500 rpm engine, it depends a bit on gas speed (the back wave might be delayed in time more than the forward wave time is decreased by gas flow changing the exact length a bit from standard organ pipe math) and temperature. But if that's obstructed by the transmission or transfer case or cross member you could go around 67" with an H at 33" or 16.5." the x on many cars would actually be better placed near the rear universal than as soon as it fits by this math. Shorter for an 8000rpm engine and longer for a 5000 rpm engine like a stock cam or a long runner efi manifold like Ford and Chevy used in the 1980's on tpi and 5.0/5.8l engines. Those numbers are for 8 cylinder engines, the numbers for 12 cylinders may be shorter. The more pitch you want you would divide the distance to the x by larger whole numbers for additional reflection points. A guy who built a 5.0 Ford (yes classic 5.0 not Coyote) powered BMW for budget racing built a 180 degree header to get equal pulses and a super car sound. It worked but this type of build often forces you into primary pipes that are too long. It might work on a 5.0 because the intake is also very long. But it's not always best. So he then replaced the hand built headers with equal tuned length headers and used a triple x pipe to get the super car sound. So he had a pushrod V8 with odd firing banks not known for that high pitched howl and extracted that sound from it on a full length sedan simply by pinching harmonics using redundant x pipes ! Long pipes tend to mean lower pitched rumble but it can be manipulated easily by causing intentional reflections at equal interval lengths.

      I liked the comment!!! But we didn’t build that one for sound first was my main point. If we did, it would have been a different plan of attack.
      The goal was to try to affect a performance vector I think no one else had taken advantage of- the sound was questionable because we had never done it, but optimising scavenging via order, would only benefit?!?
      So it was kinda let’s try THAT and see how it turns out. But it made power so mission accomplished! Happy to still have your vote of confidence on our ability to massage out good sound, it’s just two different goals.

    Years ago I had a 5.0L V8 with a single 2½" pipe. It had an expansion chamber near the transmission (very similar to a Catalytic converter that had it's insides removed), then a straight through pipe through to a rear muffler. It sounded OK, but I started experimenting and hole sawed another hole next to the muffler tailpipe into the Helmhertz chamber at the back of the muffler. This hole lined up with the internal perforated pipe inside the muffler, and I inserted another short pipe into the hole and attached it to the existing tailpipe with hose clamps so that it could be adjusted to insert into the muffler chamber by different amounts. My mate and I took turns driving WOT and the other listening as we drove by. We adjusted the length of the new tailpipe until we got the best sound, then welded it in place. The results were amazing. Not super loud but more like a sub woofer effect, especially at idle. I guess it may be due to two out of phase sounds being produced? Strangely blocking either pipe had the same effect at making it quiet to about the same noise level. I had many people ask me who built the exhaust.
    So my question to @FluidMotorUnion is, have you tried placing the megaphones in each pipe at different locations to each other. ie, one close to the engine and one further to the rear.
    Or, placing them at close to the same length, but making a sliding connection on one so you can adjust it along the pipe by a few inches and move it slightly to experiment with different positions along the pipe while ethe other one remains in the same place.
    Please tag me if you try this, as I would be very interested... even though my revhead days are pretty much behind me.

    Just changing the outlet tip can make a difference.
    I have a 2000 silverado with flowmasters. It had dual 2.25 outlets. Changing them to an oval changed the tone. Megaphone of a sort.

      Ditch the flowdisasters and get some straight thru style mufflers. Sounds way better

    Regardless of any subjective choices and fluid dynamics theory, it would appear that you do top-shelf exhaust system fabrication. Very, very clean and tidy, sirs. Well done!

    Sounds much better than my S65 did. Would like to see you guys test the Brilliant Exhaust merge pipe on these as well. Same style merge that Gintani made popular on Aventador.

    Interesting concept using the megaphones. I'd love to see this tried on an already great sounding NA engine, like a LS7. It would also be interesting to try using the megaphone and reducer going into and out of a high-flow cat system. That might flow better with a smoother transition into the inlet side/face of the cat, and the cat would tend to straighten the flow/soundwaves, before reducing back to a traditional pipe side. Only concern might be getting the cats close enough to the engine with the megaphone... But using the C6Z example I mentioned, I think one could place them in the early part of the tunnel with success. Could be interesting to experiment with!

    Totally awesome, now I'm not a big budget dude but I appreciate the sound and I'm looking at my Jaguar XFR for both power and noise upgrades in the exhaust, the builds that FMU does makes for great inspiration. Cheers team.

    • @FluidMotorUnion

      Hopefully it’s something you can try and get into your next system without being intimidated by those who say you need to be an engineer 😂. Try it see how it sounds, move it, try it again!

      Ha I have been fabricating an exhaust for my Ford Sierra xr4x4i (Ford Merkur in the US, as I live in New Zealand) and making changes to it and not being a competent welder and hence practicing on the Sierra, but since I'm into building my own I take inspiration from your works. But once I get the welding done then I'll progress into my more advanced cars.

Definitely look into megaphones more might be what I’m looking for and keep me EPA compliant here in Cali :). thanks for the overview great video and insight

    Fun fact a expansion in the exhaust like that creates a pressure wave that pushes backward creates back pressure thats why 2 stroke engines need that and thats why i know lol

    The original "Ramchargers" drag racing group from back in the late 50s were a group of Chrysler engineers that were interested in drag racing. They had a very "sciencey" approach to modifying their "High and Mighty" 40s coupe. Those guys had a tuned megaphone hanging out of the bottom of the wheel opening on the front fenders for each cylinder of their Hemi engine. They also used long lengths of hose, similar to radiator hose, to run from each intake port out through a hole in the hood, and up to an intake plenum up on top of a "tower" on the hood. The carbs were WAY up there on top of the tower. The intake runners were very LONG. The intakes and megaphones were both tuned for 5000rpms, where the vehicle was shifted. The car looked strange for sure, but it worked well

    i did a muffler/resonator delete on my lexus gs350, added vibrant bottle resonators and 3 inch tail pipes and it sounds really, really good for a V6 in my opinion.

    Beautiful explination and now it makes me want to try it. Obviously cylinder count has SOOOOO much effect on the sound and so does displacement But it would be awesome to figure out a formula that can closely give you an idea for how much length and size of the megafone for a specific sound range. Wonder how well itll do on a 3L twin turbo V6.
