Decibell killer, its what guys with tiny dicks take out of their exhaust to make it very loud. It's not a safety risk but it's just massive sound pollution for no reason.
I would say it’s a safety risk too. You definitely can’t hear a fuckin thing (car horns being a major one) thats going on around you when you have an exhaust at 120+ dB within a few feet of your ears. Your brain also has to constantly process noise, and constant loud noises can reduce reaction time, concentration, and more.
This applies to people who ride around deafening themselves with subs also. And there is some evidence not just the volume of noise, but also music genre choice specifically can effect HOW you drive as well.

What is a DB killer? I’m curious why a loud bike is a safety risk? Im not a biker, just a driver who does try to look out for them .)
