They are a snail shell type, slightly larger than stock ones but they fit fine. They're made in Italy but they aren't Fiamm. Get a high tone and a low tone horn. They mount up in the same place as stock horns. When I honk the horn, it is hella loud with the sound of an old Buick or other old time tank. The desired effect is achieved when some jack-ass starts drifting over into your lane. They don't think it's just a tiny sports car whith that wimp-assed 'neeep neeep' that sounds 2 blocks away, and they snap right back into their own lane(usually! Use caution anyway). I can look and see what brand they are if you want.
