I love i30n very much. however, in raceroom , the backfire sound seems much lower as compared from the real car. Tried to struggling ingame sound settings and windows audio settings( soundbaster ae-7 and auduze mobius), but still cannot achieve a satisfactory result. It is really not a short disparity when comparing with youtube video showing at cockpit view. The strangest part is that the anti-lag sound is clearly heard from other viewpoints of the game.
