I swapped out my horn yesterday for a 21.99 air horn that I bought at JC. Whitney they fit right behind the grill and sound decent. It isn't a real deep sound but is 5x better than what came with the h3.... The bolt that came with my kit fits perfectly where the old horn was mounted. I did have to cut the OLD horn's screw off so I could get it out.
