YOU GOTTA BUY THIS HORN KIT NO CAP

Definitely the best upgrade I've done to my 2011 Dodge Ram 1500 foreal! This kit is absolutely insane LOL! When I say insane I mean bring a spare pair of underwear INSANE! Between the deep train horn tone and the loudness of them you could roll up on a set of railroad tracks and have a battle with a train!
