The exhaust system is an indispensable part in any internal combustion engine, being responsible for the scavenging of burned gas discarding the excess heat. The exhaust system can extremely affect the engine cycle efficiency, where the pressure waves can ease or disturb the gas scavenging process. Small changes in both diameter and length of the exhaust headers lead to sensible variations in the engine�s performance. A proper manifold design can save significant amounts of fuel. Thus, the focus in this paper will be comparing the various designs of exhaust headers and representing their effects on the engine performance. A wide range of designs are modelled in this paper, which will aid in optimising exhaust systems. An analytical approach is used to determine the most efficient exhaust headers design. The engine is modelled based on a Honda CBR 600 RR with a modified intake system, where a restrictor is installed at the air inlet, while the power train is modelled to simulate a formula student car. The model simulates the engine and its effect on the car�s overall performance. Various exhaust configurations are implemented using this model, in order to demonstrate the effects on power, torque and efficiency for each design. The results show that simple modifications to the exhaust headers can save a considerable amount of energy compared to the conventional design, and in the same time maintaining a better engine performance.
