Transport models are often being used to simulate the hadronic rescattering (or so-called afterburners) that is thought to happen at late stages of heavy ion collisions at RHIC and the LHC. In this work we use a new transport model, SMASH (Simulating Many Accelerated Strongly interacting Hadrons), to investigate the specific effects of including such an afterburner on hadronic observables. Amongst others, we notably present results for yields, elliptic flow and mean-pT, with and without SMASH. Effects of using Cooper-Frye sampling algorithms that conserve quantum numbers (strangeness, baryon number and charge, specifically) and energy-momentum on an event-by-event basis are also investigated.
