Without seeing dyno and ignition curves, mapping or flow data it's hard to give an educated answer. There is...allot of voodoo going on there.
I would say it is quite the psych job.
If I end up going to the AX in Reno this weekend I will do that.
You and aees gave perspectives and replies that are good. Thanks. That’s basically what I was wondering.
I’m not sure why this immediately turned into “muh riding areas” and stuff. If the vision behind our sporting events is more conversational then sure. That makes sense. When the noise discussion happens like 90% of the time it’s framed as some kind of impending danger to health and sustainability.
Thanks for not calling me a narcissist too🤣🤣

I have a feeling most of the people on this forum are the “turn that racket down” type crowd.
People that go to motor sports events enjoy the sound; weather it’s a dirtbike or a race car, there is nothing else to it. Without that, it's just not as exciting.
Hearing the engine rev while a rider throws a whip. Feeling the vibration in your body at a NASCAR race.
40 riders all on the gate rev bombed before the start of a Pro National is a magical feeling.
It you go to a Supercross or Pro Motocross race and have complained "it's too loud" then you probably need to change your tampon.
Now a local track, I totally get it.
They don't worry about noise at NASCAR races, Moto GP, Monster Trucks, Local Mud Bogs/Tractor Pulls, Indy Car racing, Drag Racing, I could go on and on.
Formula E failed because no sound sucks.
Bro, your last sentence. You just said this:
Think about the bigger picture: Its all about the trickle down effect on production bikes/aftermarket parts. No one is going down to their local monster truck dealership to buy one and roll down first street with open headers....zero race development impact on production cars. On the other hand, the exhausts on the race bikes ARE being marketed to the general public (amatures) and there is a benefit for ALL riders if development includes a cap on DB limits that translates to more places open to ride (or not closing more land due to sound...)
It was sarcasm bro
For anyone that thinks sound isn’t important, listen to music in your car then listen to a 100+ choir and band.
Sound is 20% of our perception.
nothing gets me juiced like a 450 cracked open.
This is exactly the reason. The professional sound regulation is a result of the manufacturers efforts to reduce the noise levels of their production bikes for non-professional use. A massive chunk of the reason for this comes from the need for it in Europe, and the manufacturers don’t want to build a North American spec vs a Global spec bike anymore. Bringing a consistent value to the sound limit globally (hence why the AMA is jumping all the way to FIM/MXGP’s dB level) allows the manufacturers to have a more “level” playing field among themselves if they just build a global spec bike.
I also believe that I read or heard somewhere relating to this that the rule is being pushed by the manufacturers themselves, though some of them weren’t quite ready for it to hit this year so it got pushed back.
At St. Louis SMX playoffs last year I was in around the 10th row of the second from the floor section, and my Apple Watch was giving me noise safety alerts the entire time of 100+dB. I wore hearing protection throughout the event because it genuinely hurt my ears.
It just plain looks more correct for the pipe to be in that area. It's what we are used to visually, surprised the aftermarket didn't do that immediately in 2010. (This would make a 2010 yz450 with the tornado pipe run significantly better as the tuned length of those bikes is a bad compromise, hence the solution in 2014.)
Or being an internet troll.
It’s funny because I’m genuinely not but anyone over 30 cannot comprehend when disagreement and banter combine. The elder mind cannot process alternative thought.
My 20 hour 500 EXC came with a straight through MX pipe. It was unbearable just sitting on it at idle let alone riding it slowly. I found a new takeoff 501 can that still had the peferated end cap. Put it on, and instant relief. Bike it still plenty fast to lift a wheelie in 1st through 3rd without much effort. If I could make it even quieter I'd do it.
What all is being done to address airbox noise in Europe? Or is exhaust the main culprit?
The arrogance of your ageism is nauseating….
