Improve the sound of the Skoda Fabia RS Rally 2

Unfortunately, it doesn't sound quite like the real sound of the Skoda Fabia RS Rally 2. It sounds more like a Skoda Fabia R5, but with a louder sound from the relief valves. In the case of the Toyota Yaris GR Rally 2, the sound is quite realistic. Please improve the sound to make the Skoda Fabia RS Rally 2 more realistic.
