Running along with another GS both with aftermarket pipes we sounded like a WW2 bomber as the engined notes hummed and throbbed. No other bikes sound like that.
My Akra system now has a fairly open baffle in one can and a full fat dB killer in the other. It still pops like a goodun but now doesn't wake people in the next village.
The Afriflow system I had on my bike until very recently was a straight copy of the Akrapovic 2-into-1-into-2 system, in stainless steel.
I must admit, I didn't like it. It weighed a ton and actually cost power.
I retained the Afriflow headers with de-cat, and had Tornado Developments graft on a SS/carbon silencer with a slightly longer-than-normal bridge pipe.
You can feel - and hear - the difference.
O joy of joys to live in a country where the filth wouldn't know what a dB meter was if they tripped over one...
