Like mine and I put the stock electric horn inside the fairing. Tied into the horn wire right out of the harness and there was a tab with a hole right at the bottom of the fairing cap so the horn faces down below the headlamp. Much more louder....

 

I used my HD air horn just 30 minutes ago...

I had a cage try to use the right turn only lane to shoot past all of us law abiding "left-lane-goes-straight" folks and then try to force her way into the flowwhere I was riding. The long, loud blast jerked her back into reality and out of my lane with a dazed look on her face.

I just smiled and rode off...

I got them they work great.

 

With this air horns that have the dual trumpets....does anyone run them on a bike with lower fairing? If so do they fit ok? And does the fairing lowers have the effect of blasting the sound back on you? I've been looking at a lot of them and had almost settled on the mini-beast only because of the issue with the turmpets.
