dB unfortunately has many factors that can contribute to how loud an exhaust is. Air temp, humidity, which way the exhaust is facing.

Most of the N1 type exhausts hit around 95-98dB. If you use the silencer it brings it down to about 85dB (give or take).

I know some shops can test it for you or you could go to Radio Shack and purchase a sound meter.
