If you fail, (a simple hand clap is about 105 db) you are seeing the state ref and a fine of about 1000 bucks along with all other fees. You know, they are looking for smog stuff too. You got smog pump, cat, and.... Mod motor? Be careful what you wish for.

Jeff, I thought it was 95 dBA at 20’. Compares to standing right next to a running belt sander, or standing 50’ from a running jackhammer. If lots of cars/bikes are exceeding this sound level, it can be unpleasant as hell. You live in a hilly area, like me, right? We’re frequently hearing people opening it up as they drive uphill a few blocks away. It’s loud, and can go on at all hours. I’m not a get off my lawn type about these noise levels, but life would be nicer without this jackassery.
BTW, isn’t Laguna Seca’s noise limit 92 dBA at 50’?
