Loud vs quiet exhaust?

Man card redeemed.
Unless, you know...he heard you before you even started passing, at which point ones sense of observation might cause most people to say to themselves "Hmmmm, something is there, I hear it" and maybe take a second glance (or make a different decision) based on said observation.
Trying to equate this logic in reverse is ridiculous and grasping at straws.
People don't SEE us on bikes because we're small.
Go to court and say "I didn't see the tractor trailer, that's why I hit it!" and you'll give the judge a good chuckle. Now, people who've hit cyclists use that excuse (however ridiculous, but valid) with motorcycles all the time, as we all should know...and it's completely accepted as fact.
C'mon...
You need a filled eight passenger minivan to keep the man card nowadays, man.
Here's a cute set of notes for you [funny notes left on miserable parking jobs]: http://thechive.com/2015/11/05/funny-notes-left-on-miserable-parking-jobs-17-photos/
Thats not what I meant, the tractor trailer should run me over because he didn't see me in my truck while I was passing him.
Your obviously part of the loud pipe crew so I understand.

Perhaps not but there are other situations where being heard would be beneficial and add an element of safety.
And BTW, motorcycle exhausts are basically omni-directional. When you see a MotoGP race or watch Isle Of Man TT racing, do you hear the bikes coming down the straight before you see them, yes or no? Or are the bikes traveling faster than the speed of sound?
Agreed.
Guys put headlight and taillight modulators on their bikes, wear reflective gear, drive defensively, etc etc etc...but want to toss out an easy (and not necessarily obnoxious) element of safety in sound.
No.
Part of the problem is that debates like these end up conflating the concepts of obnoxious/irritant levels of noise and the benefits of being heard on a motorcycle in traffic. Some simply have no clue (like those that think a rear-facing exhaust emits no sound forward...), some are unable or unwilling to separate the former from the latter, some are simply unwilling to cede that there are benefits to being heard because they should be relying on only one thing (e.g. skills) for basically all of their safety. I suspect the rest are moderates that come down seeing benefits to being heard and agreeing that it's possible to achieve this without being obnoxious.
Take a video of your bike idling in the garage. I challenge you to show a place -- presumably toward the front of the bike -- where the sound of the exhaust disappears. Please post it to Youtube and provide a link.
The problem is the sound is being bounced off the walls/ceiling of the garage and it's sitting idle. Ever notice how your bike sounds different when standing infront of it as opposed to behind it? If sound from a motorcycle isn't directional then why would they take sound level readings from the REAR of the motorcycle and not just at a certain distance from any direction?
Just for ***** and giggles I googled zx10 fly by. Wow I could really hear that bike accelerating up to speed...

I sure as hell heard it for the 3 gears AFTER it passed though.
Goodnight (atleast until that damn pirate rides by around 9-9:30).

Sound pressures waves travel in all directions from the exhaust outlet. Yes, in some directions the intensity is higher but you still hear the bike from all directions, in the garage or not.

At the beginning of the vid I hear the bikes before I see them. How is this possible?

Well put.
If someone comes here with a hard-assed "I run straight pipes, they save lives, screw you, I don't care if your dishes rattle in your kitchen when I drive past your house" attitude, I think people are right to chastise that. On the flipside, to have an attitude that driving a silent/quiet bike and relying exclusively on your super duper mega elite invincible driving skillz is going to keep you 100% safe in every possible scenario forever and ever until the end of days, well, that's equally deserving of chastising IMHO.
Better yet, here's a video that took me about 5 seconds to hunt up on YouTube. Skip to about the 0:50 mark (just before police karma hits, but that's another story) and observe how far out you can very clearly HEAR the motorcycle while it's coming at you.

Again, the old "you only hear the exhaust out the back" argument is ridiculous as well. Dricked, your example is a poor one - iPhone 4 (crappy quality in that generation) on a windy day on top of it doesn't equal a good recording platform.

Precisely.
Great example. People should look up "the Doppler Effect" and how it is that the sound of a train horn changes tone as the train passes but more crucially notice that it remains audible even though the horn trumpets are forward-facing as the train moves away from the viewer's vantage point.
Do you get discounts for hi-viz? For headlight modulators?
SF didn't give me any sort of discount for having taken an MSF course nor for my bike having ABS. Why would they do it for an exhaust?
And why are you tying a safety benefit to monetary gain?
I get the exact same insurance discount as I do for having a horn. A big fat zero.
That doesn't mean I don't want the horn or discount it's effectiveness as a noise making device that gets other people's attention.
Thread is hard to follow. Please quit trying to be reasonable and rational. Get with the program, choose one of the extreme positions please.
