Decibel level of Kooks exhaust

All,
Anyone know if Kooks tested the decibel outputs of their exhaust systems?

I have a 1 7/8" long tube headers, high flow cats, and the "sleeper" cat-back exhaust installed on my 2010 SS. I'm looking to export it to NZ, but they have a 90dB noise limit for street use. I downloaded a decibel meter app on my phone and recorded about 80 dB at idle, but i know the tests are a bit more extensive.

Just curious to see if there is already tested data out there.
