<p>The device comprises a single metal housing (8), fed by two exhaust pipes (17a,17b), containing two catalytic converter units (14a,14b) and two silencers (15'a,15'b), positioned alternately so that each silencer lies alongside one converter and end to end with the other. The converters and silencers are held in place inside the housing by supports (13a,13b,16a,16b) and are fitted with guides (18a,19b,20a,20b) for the gas flows.</p> |
