701 with b pipe mod, h20 waterbox too loud

[1xxrjxx1]

I have a b pipe and h20 waterbox, fcv, in my brawler. Rage said the h20 box fits no worries so that's what I bought. The issue is like everyone else the box is crazy loud. I could add more water at the cost of power or buy a new waterbox. I'm aware.

But out of curiosity has anyone tried putting in a tail pipe stainless steel muffler silencer (similar to picture)? Or a inline resonator?
Just curious.
