The exhaust system being a critical system of any automotive vehicle plays a responsible role of improving the ride quality of the vehicle and fuel economy. The effective design of exhaust system is critical in order to ensure the required exhaust gas is exited from the engine and at the same time, the noise is attenuated. The exhaust system attenuates the noise from the engine without deteriorating the engine performance by ensuring an optimum value of exhaust backpressure. Exhaust backpressure is one of the crucial parameters that are always scrutinized by the automotive manufactures to ensure that the engine delivers a superior performance. This project deals with a practical approach to design, develop and test muffler particularly reactive muffler for exhaust system, which will give advantages over the conventional method with shorten product development cycle time and validation. Traditionally, muffler design has been an iterative process by trial and error. However, the theories and science that has undergone development in recent years has given a way for an engineer to cut short number of iteration.
