130dB @ 3000 rpm?

How loud at 5000 plus and WOT?

Are you running open pipes?

Was the sound meter used correctly in the this measurement?

Hey Gaz how's things mate,

Funny thing with the meter was I used 2 different ones over a couple of days yes they are open pipes and after 3500 they seem to reduce DBs by about 10 a bit weird but could be the sweet spot for the quad cams at 6500 it wasn't much louder only by 7 dbs unless you stabbed it then she was insanely loud lol
