Stebel Nautilous Not the prettiest horn, but at 139 dcb its pretty darn loud. Had mine for about 6 months now and works great every time. Scares people to death if you blow it when your beside them with there windows down. You can put some of the HD inserts on it to dress it up. Wish I had some pics to show you. Maybe I can figure my digital camera out one day.

 

Get a Gold Wing horn, it is loud.................
