no, but I think it's so deserves to be reworked for the effect by seeing the car from the front and from behind.
then, the length and arrangement of the exhaust strongly influences the sound. I do not claim to be able to get better, there is not really a good video of this car in gt3 version to get what should be. But considering the very good quality of most of the sounds of Fonsecker, it would be possible for him since his fmod project to adjust properly the sound.
And it is not necessary to accentuate the question with 3 ???
