I am in my 70's and a lot of my hearing is gone and the reason I have been told is loud noises. :frown: When I was younger I liked the sound of loud pipes but I am paying for it now.

Im young and love the sound but after about 5 min my ears ring without protection. I now always use plugs. And here is what a 5.5 sounds like. This user does not have permission to use the HTML BB code.
