Yes,I have one for my iPhone.Its not very accurate.Seems to pick up background noise.I guess it would give you a rough idea,but dont rely on it.
102db is quite loud.My 999S made 99db at Cadwell with a Termignoni assymetric system.
Mind you,the open clutch was louder than the exhaust!:lol

reconnect the cable I would just to be sure,there a bit hot on the noise now because of the moaning fookers,Mallory has suffered loads because of this :no

Where you hold the noise meter can make a difference too. Most of the tests i've seen are taken half a meter from the outlet at 45 deg.
Some tracks continue with the noise meter as your going round in your sessions then all you see is a black flag :no
Seems my apprentice db checker wasn't holding meter at right distance.Correct reading is 99.8db at 5000 revs standard can with flapper connected and cat removed.
