I'm with you sir, absolutely love the flames and bangs. I've calmed down since getting the tune, but when the time is right it's pure enjoyment. I still wish I could get some real audio of it, external mic definitely helped and mounted towards front of the swingarm to keep it out of the wind.
I was disappointed at no flames in the tunnel at the beginning!
So far in the past week of riding co-workers have told me they thought a solid steel plate fell off a work turn (said workers pulled on shoulder to check) and another thought someone was firing a gun at him.
