Byron's 2016 Subaru Crosstrek has our Conductor's Special 844K Nightmare Edition Train Horn Kit installed on it. This kit features our Shocker XL Train Horns that pack an intense loud authentic train horn sound! The Horn Air 844K Air System is perfect for Train Horns as well as being the perfect onboard air system. The 8-Gallon Air Tank provides around 15-20 seconds of honk time. The dual Viair 444C Air Compressors are constant duty compressors. Meaning the air system can be used to air up tires and use air tools as well as the Horns!
