    Finally someone who actually dissects a muffler to learn somthing! And then improve upon it! 🥳👍👍
    Personally I believe that the first baffle is the problem really.. The exhaust puls (moving at almost the speed of sound) hits the baffle and reflect back as if it's an dead end.
    But please keep posting your findings and experiments! 😊👍👍
    Best regards.

      The first camera is the one that does the job of attenuating the dB. As the sound wave bounces and collides with the incoming wave, the dB decreases. Then the wave passes to the second room and the same thing occurs, for a longer period of time and so on.

    I have the same exhaust, love it for many reasons, initially was bot too loud for my taste (although much nice4 tone) so i replaced db killer insert for 58mm for open exausts (like those in scrabmlers) almost as uiet as the original, buts sounds beautifully, not to mention the weight, placement and looks

    Thank you very much for your interesting Video about this muffler inside. I wonder how simple he is.

    Hey! What happened to the end of the exhaust conversion? You cut, drilled, and then fitted a half-finished stub. But then no sequel. What did you do with it? What was the effect? You still owe this if you've already started. Please post the sequel as well. I'm specifically interested in the factory muffler, what did you put together? Mine is also a Tenere 700 equipped with a welded muffler. Of course, the killer of the American one can be removed. It is held by 4 screws. Of course, America got better than that. I'm waiting for the video. I wish you a nice day.

    Nice video, thank you! :) Did you measure the diameter of inside pipes? It really interests me.

    I think back pressure is a lot more impacted by the catalytic converter than the muffler

    I personally have modified my own stock muff.
    First thing I did was take a hole saw to the end and put the cap back on. Wasn't obvious but definitely let it breathe better and sounded "ok"
    Was still very hollow and empty sounding and my friends described it as "fluffy".
    I then had another go at it. I cut the ends off and remove the baffles from the outer skin.
    I replaced the guts with a perforated core, tapering it from 2" -3" at the end cap and squared it to fit the cap. I kept the cap as the end so I can replace the fibreglass in time.
    Its louder yes. But I feel it's the right amount of noise. It sounds fantastic and the tire noise and wind noise are still louder than the pipe on the highway.

      Nice work! Personally, I hate repacking fibreglass in mufflers, hence why I was curious to understand the restriction in this one. I haven't yet got around to modding this one and trying it out, but I have since found that Colin at RIDEWITHME has a kit available to do exactly what I planning on - cut the end out with a holesaw and then bolt a larger diameter outlet on. This mod is a little less crude than simply hollowing it out with the holesaw (I did this to an XR once as a kid and got the same symptoms you described above - louder, but not a great sound and almost certainly counterproductive to exhaust flow due to the low velocity outlet). I'm all about supporting clever thinking, so if anyone wants to try improving the stock muffler without introducing fibreglass they can find the kit available here:

      In the mean time, I also caved and bought a cheap fibreglass packed muffler to trial ;)

      @@jroko6709 IMHO I don't think any adjustment to the tip will yield a good sound or tone. It's just too empty and hollow due to the design.
      Knowing what I know now, id absolutely buy a cheap can for the end and call it, welding the stock can was an absolute pain in the backside and its still heavy.
      If I change it again I'm planning on putting a small hotdog type muffler where the cat is under the engine and just run a bit of straight pipe out the side where it sticks out from the footpeg, or maybe up under the tail nice n tight

      @@klampykixx That's kinda where I got to as well - for the sake of a couple of hundred $, a cheap aftermarket one is a pretty reasonable option. There's more issues to the stock one than just noise and restriction - it's heavy and very bulky - to the point where it is likely to damage the swingarm if you drop it etc.
      The top exhaust hanger is also in an annoying spot and can't be unbolted. The die-hards amongst us will cut it off to fit high mount mufflers or panniers, but to the letter of the law this writes off the frame. Of course, Yamaha could make everyone's life better with the 2022 refresh having a new muffler with a bolt on hanger...

      My thoughts of the muffler under the motor, would actually allow me to tuck some straight pipe on the inside of the hanger and nice n tucked under the tail fairing.
      A bolt on exhaust hanger would make tons more sense, heck they could just use the pillion peg design to hang it off the tail, it's the right shape, just take the peg off...
      But I digress... lol
      Cheap perforated core can ftw

    Thanks for this video. Do you know what I could do to make my tenere 700 quieter?

    Back pressure is a myth for 4 stroke engines.
