Most US states set pass-by vehicle noise limits between 80 and 95 dB. Modified exhausts routinely crack 100. Boom Catcher logs the exact number — so the conversation stops being "it's loud" and starts being evidence.
Decibels are logarithmic. That means every +10 dB is 10× the acoustic energy — and sounds roughly twice as loud to your ear.
A single modified exhaust at 100 dB drowns out ten thousand conversations at 60. "It's just one guy" isn't just one guy.
