The overall aim of this paper is to refine the design and manufacturing techniques of the exhaust system of
FSAE cars. The main objective of this paper is selection of ideal geometry of the 4-cylinder engine (GSX R600) exhaust
manifold in terms of optimization of back pressure and reduction in gross weight of the exhaust system. For achieving this,
we have considered runner length and diameter, muffler diameter, flow of gases in the exhaust manifold, volumetric
efficiency, etc. Softwares used in design and validation are Solid works, Ansys and GT Suite.
