Found this set of Nathan K3s and tank/ air compressors http://www.trainhornforums.com/showthread.php?t=4824 Sent from my iPhone4 using Tapatalk.
how much are just the horns cuz five gallon tanks are 45 dollars, 1 valve is 20, and a compressor for a train horn setup would be bout 100, so 165 minus horns idk why its a 1000 dollars for these kits u could buy it seperate sooo much cheaper
oh and haha those compressors are rediculously huge for air horns, im running 1 400 for my whole truck not 2 444's lol
