I just traded my Ultra Ltd for a Road Glide Special and I want to put an air horn on. It is one of the first things I do because it has saved my bacon more than once. My personal fav is the Stebel but the way the mount is designed makes using the HD horn mount difficult and the last one I had literally shook apart. I am looking for plug and play suggestions that will use the existing horn mount and is LOUD. Thanks in advance.

 

first welcome from Spartan Country Michigan.
second, check out the mini-beast from Custom Dynamics. a bit pricey, but loud. pretty much plug and play..... I like it.

 

I found a few discussions about this very topic.

 

I was going to get one once. I saw the Wo-Lo...heard it and liked it. I think it was under $100.

 

I got the Mini-Beast and it is about as plug n play as you can get and it is LOUD..

Not an especially good photo, but I really dig my Rivco. Retro-looking, and it makes the silly bastards in the cages drop them cell phones in a heartbeat.

Note: Finding a place to mount the compressor is another story, though. And don't listen to anyone telling you "Aw, that doesn't need no relay!"

 

I, too, went for the dual trumpet air horn. It has a compressor for each trumpet. It didn't function without a relay. I had it measured at 134 dB. I'd consider that rather loud.

 

That's a minibeast on my rg. I don't like trumpets, had a couple come apart over the years from the vibration. Its plug n play and loud.

 

I've got a minibeast on mine. But it only works sporadically. The other times, it causes the ECM to though a current-draw code. So it clearly isn't plug and play after all, and needs a relay to be reliable. I just haven't got around to it yet, as I tend to drop the clutch to raise attention rather than use the horn in any case.
