I am interested in those horns Chief. Think I would like to install them where my air cleaner is located ( it is just there doin nothin, installing the hypercharger made that one irrelevent, just chrome filler between the twins). And there is a cross member connected to the twins. The photos I observed looks like I could make it work... Thoughts?
I've seen them positioned there on Harleys. No reason why they shouldn't work on ours in the same position.
My only concern would be bumping them with your knee. But I think if you work a nice snug bracket it won't stick out any further than the current air box cover... ie about 4 inches.
