I'm sure there are plenty of people here in Australia that would be able to build the same thing as Sam. A mate of mine got some nice silencers made up for his roadster here in qld also .And I'm sure if I show them the pic and tell them what I want they will be able to build them and the best part is they will be available to buy whenever .Sams are great but we need new options that are actually available for more than three weeks
