LOL - you mean the long unit?
They need to call it the "Quiet? My ass!" silencer.
I think it's probably about >2% as loud as the shorty.
The Moskito tested at ~ 120 db with a 500cc setup and the long unit at Little Sahara a few years ago. (5' test on an asphault surface) I'm not sure how much packing was in the can, but I wanna say it was a pretty fresh unit.
