The intake and exhaust system shapes are very important factors in the gas exchange process of the combustion engines. That's why many investigations are related to the improvement of their geometry in order to maximize engine's performances or lower its emission values of the exhaust. Modern approach in such researches means use of numerical simulation codes, which give us individual geometry of several engine parts. the production of numerically improved part, they must be tested and evaluated with the experiments. The paper deals with the influence of the intake and the exhaust characteristic (diameters, lengths, shapes) on engine power, fuel consumption and emissions. The optimisation procedure together with the optimized measurements for the intake and the exhaust are also shown. For the simulations the AVL's program BOOST was used. It proved to be accurate enough for the four-stroke internal combustion engines in the course of our previous work
