Exhaust silencer design in motorsport is a matter of establishing the best compromise between rules compliance, mass savings and engine restriction. A design methodology that acknowledges these difficulties is likely to be desirable to ensure that the best solution is always provided for the competing team. The present work takes into account a comprehensive analysis of mass versus silencer restriction matter, based on simulated lap times to find the optimal compromises. A thorough discussion concerning the different techniques concerning passive noise control is held, establishing a widely comprehensive concept study phase. Further optimisation of the best concept is conducted via Design of Experiments. A final finite element analysis is conducted in order to assess the quality of the proposed solution across a larger range of frequencies and confirm the design formulated so far as effective.
