I have "louder than stock" pipes because I like the sound but not for safety...I consider that just a side benefit. Another benefit with my add-on pipes is they are quiet enough in the neighborhood but loud on the highway.
Denying that louder pipes don't provide an "additional" safety factor is ignoring your common sense AND experience...and yes I have also read the reports/test about "noise generated by a moving object, etc".
I'll trust my 34 years of riding on this topic.
