With all due respect to Akella for his efforts (I really appreciate all the guys who go to special lengths to get OEM stuff for us, at a good price), I picked up these http://www.rallylights.com/te16-compact-trumpet-horn.html as just about any horn that is a dual blaster of 400hz and 500hz will do. Sounds just like the muscle cars of the '70's. Good'n loud. Got a pair back in '08, for $32.50 shipped. They're even cheaper now. Pretty much plug n play.
Now if it's drive train components, or other mechanical aftermarket...then the details are much more important. These have worked great for me! I still turn around when I honk the horn and wonder...who's that???
