Here's an easy way to get started with an all inclusive air horn kit by Kleinn, one of the leaders in automotive air horns. Dual chrome air horns, two chrome all metal trumpets 8.5' and 6.5" in length. Compact with a high pitch painful sound. This compact horn and tank combo will fit almost anywhere. The compressor is sealed and the system includes a remote intake filter and check valve to prolong the life of the compressor. At an honest 151.4db, this one really delivers at an easy "get-in" price.
