What is/are the loudest stock exhaust sound(s) on modern cars?

-Ford Mustang Shelby GT350 - 92 decibel (which is near the 95 decibel limit for California USA)
-Jaguar F Type SVR V8 Supercharged - 68 decibel
-Lamborghini Aventador V12 - 70 decibel

So, at 92 decibels, I guess the Mustang GT350 is the current king of the noise? (for modern stock car)

P.S.
Surprisingly, I thought that a naturally aspirated V12 would take the crown......but my guess is that European noise regulations are stricter than USA/NA noise law.
