I picked up one of those Stroebl 139 dB air horns from Aerostitch a couple of weeks ago. I painted it with the closest color to CP Blue that I could find at the local auto parts place. It's not an exact match but it's close enough, especially since it's hidden up under the front fairing.
If anyone's wondering, this mother scratcher is loud! It draws enough current to require a relay or it's no louder than stock. I ran 12 gauge wires all the way to the relay and then to the horn. The stock horn harness plugs right into the relay. It's all fairly tidy. I did have to bend the stock horn bracket a bit, but everything seems to clear full left to full right.
