Abstract—The increase in power is a primary need in the preparation of a competition vehicle. In the present investigation, the exhaust manifold was optimized through the dimensions and configuration for a Suzuki Twin Cam vehicle with a G13B engine. A one-dimensional engine model was applied in the OpenWAM software, modifying the configuration of the exhaust manifold and the lengths to increase the performance with respect to the original system; the design of the most optimal manifold according to the simulations was built using two methods, bending (type A) and step header (type B), which was verified in the experimental test on a roller dynamometer to obtain the characteristic curves of the motor. The results, with respect to the original system, show a power increase of 8.41% and 10.33%, according to type A and type B construction, respectively; as well as an increase in torque of 3.26% for type A and 8.83% for type B. The results of the characteristic curves of the 1D simulation motor show a difference less than 9% with respect to the experimental tests, ensuring the computational process
