HornBlasters Shocker XL
I purchased a scratch n dent tank first, it was fine, then an open box set of 4 shockers. For now I am filling the tank with my shop compressor, maybe one day I can pick up a 450c Viair. I have only used the horns for friends a few times but every time they about come out of their shoes. Extremely loud even when they know its coming. I used flat bar for a frame, then mounted pointing down under a Silverado front bumper. The tank is in the bed of the truck. Video's do not do these horns justice. Buy a set and you will see for yourself. I also have a WOLO 877 4 trumpet set. Doesn't even compare to the HornBlasters. Love em.
