Dude I have the same setup, minus the 3 gal tank, I have the 2.5gal tank. These horns are loud as fuck! I had the switch to turn them on and off, this one time a cop pulled me over he asked if I had train horns and honked the factory horn and told him fuck that my truck is stock, thanks have a nice day. Oh good times lol But G/L with the sale bro!
