496 Mag db?

[wantacat]

Anyone know the db rating on a 496mag above the water line?

I have an HO above water that I think is pretty loud, but it managed to pass right at about 86-88db, no swim step.

Marina showed me at 74 below the waterline. You should be close above the waterline.

Our 496 HO was right at 94 each. 86/87 after Rex silencers. Dont know the difference between the HO and the mag though.

I've tested a few against the CA test procedure....mid 90's on them with above water exit unmuffled.

496 HO above the water line will blow 93-94 db's.
