means systems which are fundamentally different in one of the following ways:

2.4.1. systems comprising components bearing different factory or trade marks;

           2.4.2. systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;

           2.4.3. systems in which the operating principles of at least one component are different;

2.4.4. systems comprising components in different combinations.

           2.5. "Component of an exhaust system" means one of the individual components which together form the exhaust system (such as exhaust pipework, the silencer proper) and the intake system (air filter) if any.
           If the engine has to be equipped with an intake system (air filter and/or intake noise absorber) in order to comply with the maximum permissible sound levels, the filter and/ or absorber must be treated as components having the same importance as the exhaust system.

3. APPLICATION FOR APPROVAL

           3.1. The application for approval of a motor cycle type with regard to noise made by motor cycles shall be submitted by its manufacturer or by his duly accredited representative.

           3.2. It shall be accompanied by the under-mentioned documents in triplicate and the following particulars:

           3.2.1. a description of the motor cycle type with regard to the items mentioned in paragraph 2.2. above. The numbers and/or symbols identifying the engine type and the motor cycle type shall be specified;

           3.2.2. a list of the components, duly identified, constituting the exhaust or silencing system;

           3.2.3. a drawing of the assembled exhaust or silencing system and an indication of its position on the motor cycle;

           3.2.4. detailed drawings of each component to enable it to be easily located and identified, and a specification of the materials used.

           3.3. At the request of the technical service responsible for conducting approval tests, the motor cycle manufacturer shall, in addition, submit a sample of the exhaust or silencing system.

           3.4. A motor cycle representative of the motor cycle type to be approved shall be submitted to the technical service responsible for conducting approval tests.

           4. MARKINGS

4.1. The components of the exhaust or silencing system shall bear:
           4.1.1. the trade name or mark of the manufacturer of the exhaust or silencing system and of its components; and

4.1.2. the trade description given by the manufacturer.

           4.1.3. the approval mark and the ECE approval number according to annex 2 of the Regulation. The approval number must correspond to the number of the ECE type approval certificate issued for the type of exhaust or silencing system in question.

           4.1.4. All original silencers must be bear the 'E' mark followed the identification of the country which granted the component type-approval.
           This reference must be legible and indelible and also visible in
