Great mod to improve the game, however there are a few things that could be improved on e.g. varying sounds rather than having the exact same audio files for each engine manufacturer, as it gets very old very quickly. Also a weird glitch with the audio that makes the right side of the car a much quieter when using Cinematic and and Broadcast, so be aware if you don't use the Driver Audio Mix option.
Overall, its very nice mod to have for anyone fancying V8 sounds in the game :)
