We all know what the factory horn sounds like! I did see this horn at the store and it will fit with no modifications.
You could try it, but you may get the same thing you already have!
Hey, that's great, DHF. This prompted me to do a little searching of my own, and I came across a LOT of detailed owner reviews of various Fiamm aftermarket horns (air horns, electric horns, etc.) on a Miata discussion list (a louder horn is a particular big issue to Miata drivers, because the Miata is invisible to SUV drivers). Here's the link: http://www.miata.net/products/pmisc/fiamm.html
The page includes SEVERAL reviews of the AM-80, and the owners were all quite pleased with it.
It might just be the same as the stock Focus horn, but maybe not...
