I'm a little late in posting this horn update, but I have had a very successful out come. I bought a car horn on ebay for about $18 including shipping. The brand is "Carrand". The Model is 3-0115 4 Magnum Blaster Low Note. It states that it puts out 138db.
I have a decibel meter app on my phone. I have no idea if it is accurate, but I figure that any error would be consistent between horns. I measured the factory horn at 102db and the new horn measured 104db. This doesn't sound like a lot, but it is a pretty fair amount since decibels increase logarithmically as opposed to linearly. In any case, the new horn is definitely louder, deeper and very much like a regular car horn.
The new horn is taller than the factory horn and there is a clearance issue with the bike frame when mounting. I used the factory bracket along with one of the supplied brackets bent into a "U" shape. I attached the horn to one end of the "U" shaped bracket and the other end to the factory bracket. Pretty simple. I do wish these things came with marine grade hardware and someday I'll get around to replacing the hardware.
For some reason, I can only post one pic here (somebody help me with this). If you look closely, you can see the "U" shaped bracket in between the horn and factory bracket which gave me the necessary clearance.
