Faurecia has developed a numerical tool which allows an automatic optimization of an exhaust line with respect to tailpipe harmonic noise. An optimizer pilots an in-house acoustic software in order to find the exhaust line configuration which fulfills the targets on the two first harmonics. The optimization method as well as the acoustic prediction tool are presented in this paper. Then, two examples of application of the methodology are detailed.
