Dragen Air Horn Kits
There are a number of great horn kits available to consumers, but there’s something about Dragen kits which I particularly enjoy. Personally, I like the variety.
While a lot of air horn manufacturers offer a number of different kits, most of them seem similar in everything but volume. Dragen kits, on the other hand, allow for differences in other things as well. The horns, for instance, vary noticeably between kits - be it one, two, or three horn assemblies.
I view this as a way for individual hobbyists to better find the particular look and feel they desire. Ultimately, I see it as a big bonus to consumers.
