Just wanted to say hello on my first post since joining a year or so ago. My horn setup is at the installer’s as we speak. I would have liked to do it myself but, since its my daily driver I had to have a quick turn around. My horns consist of two 5 gallon air tanks, two Viar 480’s, two actual Grover 1510s, and a Nathan K5LA, and a Graham-White valve. The bug bit me hard I would have to say. I’ve been aquiring parts for the last year just waiting till I had everything I needed to have it installed all at once.
Welcome to the forum! Awesome setup! Make sure to post pics 
Welcome! Sounds like a nice pile-o-parts.
What vehicle is i going in?
Welcome, seems like you have a heck of a setup

Welcome to the forums!
My horns are being installed onto my 2010 Silverado 3500HD Crew Cab 4x4. This will be my first venture into my new found horn addiction and truck customization. 
Awesome! Welcome to one of the most addicting hobbies out there!!
