To verify the Finite Element Method(FEM) model of an Exhaust System, Frequency Response Function(FRF) is utilized. Up to now. generally. comparisions of natural frequencies and mode shapes of an Exhaust System between numerical analysis and experimental result are adopted to prove completion of FEM model. However. the comparisions of natural frequencies and mode shapes are not sufficient to have a perfect FEM model of an exhaust system. Instead of these comparisions. FRF method is introduced for a perfect FEM model.<br/>
