Sound pressure waves can be muffled, its the same idea as using a suppressor on a rifle. I realize that one or two layers of wrapping is not going to silence the exhaust. I just wanted to know if anyone has tried this. Seems like an inexpensive thing to try. Any idea how much the wrap costs?
Well there is certainly no downside. Go for it.
