The majority of everyone's modified exhausts on here are not close to that 95db limit

I think everyone is misunderstanding this. The db measurement is being taken 19 inches from the exhaust tip with engine at 3/4 of maximum rpm! Not 95 db at 50 feet like race tracks measure. Hardly any modified exhaust is going to pass, let alone many stock systems. I tested my supercharged jeep srt today at idle and it was 96db on start up and 88 after it came off cold start. If I even tapped the throttle it would blow way over 95db!
