Mighty Plugs
I have a 2011 Triumph Tiger 1050 with a debaffled Arrow exhaust. Loud, so I use the Mighty Plugs. They are like Play Dough. Rub them around in your hands for about 20 secs, soften them up, and then jam them in your ear canal. Only thing that will kill the sound of that exhaust. It get them in a box of thirty or so.
