- Open up the Modified Files folder, there should be 2 folders, EngineSynth and ModularCars - Open the EngineSynth folder, and drag the following files to D:\SteamLibrary\steamapps\common\ForzaHorizon5\media\Audio\EngineSynth to replace the original ones - G_V10NM_European_Race_1_Eng.xml - G_V10NM_European_Race_1_Exh.xml - G_V10NM_European_Race_1_InL.xml - G_V10NM_European_Race_1_InR.xml - G_V10NM_European_Race_1_Int.xml - Open the ModularCars folder, and drag this file to D:\SteamLibrary\steamapps\common\ForzaHorizon5\media\Audio\ModularCars to replace the original file - LAM_HuracanTecnica_23-Engine.xml - If you wish to return to the original sounds, get the XML's from the Original Files folder and place them in their respective paths - This method is repeatable with any car so go wild with it
