Making train horn kits even louder from the factory
May 13th, 2009 . by adminWe all know train horn kits are often too quiet and need upgrades. You buy your truck for the performance, and your train horn kits for the really loud sound. Imagine a world where each train horn kit blasted you away and scared the other cars on the highway? That would be a great world, and you can have this type of horn if you install a larger air valve. Most train horns come with a 1/4″ opening, if you upgrade to a 3/8″ then the horn instantly becomes fifteen times louder. Many horns are now blowing in the 150 dba range.
