Earlier today I accidentally went over a parking block forgetting it was there, I lifted my car and went under it and couldn’t find anything out of the ordinary besides a scraped under tray which is no biggie because I ordered a Cobb undertray and a small scrape which some paint came off on the skirt. I went back to go look at the block and looks like some rubber came off. Alignment and everything is fine but I rolled down my window to listen to my car and when I am turning about a speed of 15 mph I hear a light whistle. Can anyone tell me what this could be from or what it is? Pics below of what I was able to spot damage wise. Nothing bad. Please let me know what it the whistle is coming from.
