AB In this paper the scattering between a wobbling kink and a wobbling antikink in the standard 4 model is numerically investigated. The dependence of the  nal velocities, wobbling amplitudesand frequencies of the scattered kinks on the collision velocity and on the initial wobbling amplitudeis discussed. The fractal structure becomes more intricate due to the emergence of new resonancewindows and the splitting of those arising in the non-excited kink scattering. Outside this phase,the  nal wobbling amplitude exhibits a linear dependence on the collision velocity whereas the  nalfrequency is a decreasing function. By contrast, these magnitudes are almost independent of the initialwobbling amplitude. A theoretical analysis of this new scenario is carried out by applying the collectivecoordinate method.
