If you are interested, I'm in the development process of a twin Silencer system at present.
This will fit both the Roadster and the Classic.
I've designed this to slide straight onto the stock header, and also to my Free Flow Header.
I am building my own Mufflers to go with this so as to supply a complete "bolt on" kit.
Also I'm setting this up so you can buy any of the individual components, Header, Cross over, or Mufflers separately, or as a complete Exhaust system.
Below, early development photos.
No pricing as yet.
