Hi John

Motorbike “quieteners” are all quite large diameter. Certainly more than the 1” diameter pipe I guess you have.

I think your best option is to bite the bullet and open up the silencer and wrap some deadening felt around the pipes.  The pipes should also be perforated.  I’ve just added a length of perforated pipe wrapped in silencer felt to my special (however my exhaust is 60mm diameter).  Makes a huge difference.

If you can, make it easy to disassemble the exhaust easily as the silencer felt tends to burn away after a while (according to my biker friend).

Cheers

Howard
