Powerful, insanely loud, and all in a compact kit: The Conductor's Special 244 Nightmare Edition delivers the performance you need! It features the insanely loud, American-made, Shocker Horns. These horns are ridiculously loud and, more importantly, actually sound like a train! The horns are hand-tuned in the USA to the government mandated train signal chord. Simply put, they sound completely authentic this edition also features a stealth black finish on the 444C. This is the best 150 PSI compact train horn kit currently available. It's designed specifically for smaller vehicles where larger tanks may not fit. The compressor is overpowered (200 PSI capable, constant duty, and powerful!) to ensure the best reliability, and only pulls 19 amps at its peak. At 150 PSI, the Shocker horns are simply ridiculous! This kit does come with the option to add the Tire Inflation Kit to it as well!
