Ok all. After a complaint to EPA, I've received the following test specifications for the e92 M3. It'll come in useful if you ever get pulled up and the stupid testers don't know squat about M cars.

Maximum Permissible Noise Level: 92db
Tested at: 6225 rpm

As the e92 M3 is designed to meet ADR83/00 noise limits, it also allows for a 5db(a) tolerance for exhaust system deterioration.
