OS produces stainless steel exhaust systems for various motorcycles. For the CB1100R they have developed a replica of the Honda system. As they have seperated the downtubes and silencers they also sell silencers only that will fit on the OEM downtubes. OS does only produce them in stainless steel which can be polished. However for the CB1100R we need a matt black system (RB/RC) or a shiny black finish (RD). Glenn Kirkham has found a company that can coat the exhaust parts with a ceramic matt black coating that can be polished to shiny black.

But recently Glenn has found another company that can do a glossy black chrome plating. Look at the images underneath:

Prices, all in UK pounds and VAT included (for members of the CB1100R Owners Club):

Full system: 800, chrome plating: 150 and a set of clamps: 45.

Silencers: 400, chrome plating: ca 100 (reduced if done at a batch of 3 sets).
