29. The expert from Germany presented an overview of issues with noise emissions of non-original replacement exhaust silencer systems (NORESS) for L-category vehicles (GRB-67-03), as well as a possible solution in the form of a Supplement 3 to the 01 series to UN Regulation No. 92 (GRB-67-02). Following a brief exchange of views, GRB generally supported the approach and agreed that the proposed modifications should become a new series of amendments. GRB experts were invited to transmit their comments, if any, directly to the expert of Germany, so that he would be able to submit an official document for consideration at the next session.
