I had a set of broken Fiamm air horns on my truck when I bought it. It hasn't worked for about a year and I'm coming up on inspection next month so I needed to do something. I didn't really want to spend like $50 on horns so on my last trip to the junkyard I noticed a set of horns already hanging off of a mid-80s Mercedes 300SDL. I just clipped the wiring, paid my $5 for them, and out them on yesterday. I bolted them to my condenser mounts and they sound great. Yes, it does sound european but I was into BMWs before offroading so that's ok with me . Plus, it's loud and cheap. Still, if you think about what horns you like the sound of you can probably walk through a junkyard and find some of them for next to nothing.
