Oh Yeah Andy; The Fox 59's are kind of ear splitting, but they sound so sweet in the air. I have flown at some fields where there was a building near by, and when the plane goes by it, it makes a very loud crack noise. Kind of cool. Andersons are about the same. Super Cykes are the loudest of the three in my book, and if you run gasoline in them they are extra loud. Between the Harley with drag pipes, and all the models I have flown, it's no wonder I need a hearing aid. LOL. My Wife says I just have selective hearing.
