These stainless steel centre and rear silencer boxes, made by Double 'S', are direct replacements for the standard units. Two types are available:
 

  • The sports system, which does away with the centre silencer - and is therefore cheaper.
  • The standard replacement.


The exhausts have a lifetime guarantee and the company will repair or replace any parts found defective through corrosion, provided it is still owned by the purchaser and inspected annually.
