How loud is stock exhaust in decibels?

Anyone know how loud the stock exhaust is in decibels? Is it less than 100db?

Thanks!

The Eisenmann Sport performance is street legal in Europe and North America. It offers the same db level as stock but with a much deeper throaty tone.

The Race system is not TUV approved for road use in Germany.
