Did you really expect there to be something about loud pipes?

The only way you'd find that was if there was an actual study.

"I almost broke Google looking for a large-scale, objective, scientifically
conducted, peer-reviewed study showing that users of loud pipes have a
lower mortality rate compared to other motorcyclists."

"On the surface it seems obvious that the noise emitted by loud motorcycle
exhaust systems would aid in conspicuity and cause more watchful driving by
other motorists. Yet not a single thoughtful study has been done that
supports the theory."
