Hello Vibrac,
I have tried 2 types of mutes on my goldie silencer [amplifier], the first being a VW beetle exhaust end flute. Tamed it a bit, but not enough. On evilbay I then bought these aftermarket mutes for hardly drivables.
This worked very well but somehow restricted the revving on the race cam. If you are not aiming at revving past 6.000 rpm I would give it a try. They will certainly help.
That said, no two engines are the same regarding timing, carburation, compression, cam, etc etc.
But at 14 pounds delivered worth a try rather than ditching a beautiful exhaust.

Like this one? its 35mm max but I can make a collar to get to a real measurement

A friend had an 1150 Brough outfit, when his silencer fell apart he bought a new one from the club, this is a spiral baffle type, it knocked several miles an hour off the performance so he cut it open, removed the baffles and replaced them with the internals of a modern Ducati silencer. Performance restored and much quieter.
