I love the sound rotaries, but they are easily the most painful to the ear in regards to hearing damage. An open exhaust rotary is like a percussive area denial

I love the sound rotaries, but they are easily the most painful to the ear in regards to hearing damage. An open exhaust rotary is like a percussive area denial weapon. I had one on track with me and I lifted when we went down the straight together, as they just about blew my ears out.
