a muffler is an important part of an engine system used in exhaust system. The purpose of the Muffler is to reduce the noise of the exhaust before it is released to the atmosphere. The disadvantage is back pressure can be created in the exhaust system. The literature review reveals that the exhaust gas noise level depends upon various factors of muffler. These factors which affects noise from engines. So we changed some dimensions and then measured the values of different factors through analysis. The objective of this study is to reduce exhaust gas noise level and maintained low back pressure. The performance of the muffler is assessed. Different methods are used to obtain desired outputs by inputting sound wave. The modeling of muffler is done by using modeling software CATIA V5 and performance parameters are estimated using ANSYS software tools. This study helps to improve reduce the noise level and environmental noise pollution and also minimize the back pressure which affects engine performance. The results obtained from software are compared with analytical method and they are found close agreement with each other. Later on fabrication of the muffler is carried out. Experimental testing is done for the fabricated model. At the end, comparison is done for analytical and experimental graphs and suitable conclusion is carried out from the comparison, by keeping some future scope.
