A muffler being the major element of the exhaust system, importance of its acoustic performance is essential. Back pressure and insertion losses are the components that define the muffler performance. This work aims at looking for reactive mufflers and comparing them with a combination muffler design without taking absorptive part in to consideration. The three dimensional modelling of muffler bodies was done in ANSYS R15.0 and solution was carried out using FLUENT. The pressure variation of contrasting mufflers was compared on bases of back pressure criteria. For an ordinary reactive muffler back pressure was seen to be affecting the outgoing gases. For comparative model with perforation and various chambers the back pressure was seen to be decreasing asserting the assumption of being superior
