Can BRP aftermarket muffler be quiet?

[NotThatBoris]

2009 SE5, pretty much stock all around.

New to the Spyderverse. Motorcycle Dave has already been a fountain of great info, but now I turn to the forum.
MD identified the obnoxiously loud muffler in the attached photo as a BRP aftermarket. I haven't been able to find any info on it, but it doesn't appear to have been opened up so I assume they're just supposed to be what some of my friends would refer to as "Neighbor Haters". Does anyone know:
> Can these be re-packed for better sound reduction? (it would need to be significant reduction... this thing is just stupid!)
> Is there a core/baffle available?
> Is there a reasonably priced replacement available?

My search for a used OEM or aftermarket replacement has been pretty sparse and new ones are fairly pricey. I hate to drop that kind of coin with no real idea what I would be getting.
It wouldn't need to be whisper quiet, but something significantly less that open-header that doesn't require a re-tune would be nice.
Your opinions and guidance would be greatly appreciated!
