Sounds much better than the original URD, but may I suggest an improvement?
On the first video you posted, somewhere at the 0:32-0:33 mark you can clearly hear the reservations in intake manifold, like the echoing sounds. The are present in your mod, but only when you go under the bridge or in tunnels. Maybe it’s possible to make them more pronounced, so we can hear this “intake drone” like on the video?
