Each element of the exhaust system has a different function. The element that has the greatest impact on reducing the noise associated with exhaust gas discharge is the final silencer. The design of the final silencerr has a significant impact on vehicle noise. The paper presents the study of the impact of modifications of the final silencer with a construction other than the factory one on the noise emission level of the vehicle. The tests were carried out in accordance with the Polish standard PN-92/S-04051 regarding the permissible level of external noise of vehicles.
