I guess it depends on whether or not you think this is a bad thing.
Hell, even ambulances and fire trucks drive me nuts, because I can hear them but I can’t see them and I don’t know where the hell they are. And, again, because of the Doppler effect, if they’re coming up behind you the sound waves don’t get to you very much earlier than the vehicle itself does. I once heard a fire truck approaching, and when I looked in my rear view to see where it was it was less than a car length behind me.
In any case, pipes that are loud enough to be heard blocks away are LOUD when they’re in the next lane over. Incomparably, ear-shatteringly, unnervingly, undesirably LOUD. The few situations where it might be helpful do not justify the 95% of the time you’re just making a god damned racket. Practice better riding to deal with that 5%; it ain’t hard to put yourself so the cars around you can see you; if you’re riding in their blind spot, you damn well better be aware they may turn in front of you.

Well, that is a subject of debate. Here’s a few real world examples of what I’m talking about.
I had just finished doing a carb job on a customers bike in Utah and he was driving to work. it was stock Suzuki 4 cyl, with stock exhaust and car driver turned in front of him approaching from the opposite direction. He left a wife and 4 kids. The driver said he didn’t hear or see the motorcycle. Now if he had a loud exhaust system the auto driver would have heard him, and would have looked…hopefully. We’re not talking about something fool proof here but something increase the odds for the rider.
another mechanic friend of mine did a long stint in the hospital when a lady without insurance pulled off of a side street in front of him. he was riding a honda sport bike he was road testing for a customer. The lady pulled all the way out in front of him before she noticed there was a motorcycle even there, then stopped in a panic right in front of him. Her excuse was she didn’t even know he was there. Again, load pipes would have made her look.
And I’ve know a lot of other nearly identical situations with friends and customers.
as for if its a good thing or not? Well, I think it is. it isn’t the motorcycle coming up from behind, like was pointed out above. most bad motorcycle accidents are because of people who are looking right at the bike head on and still dont see it.
