Headly Bullies
Just got them, call them directly and bought it of them, they claim to have the latest ones. I'm happy with them and they're very loud. I mounted the air horns behind the bumper on left crossmember, used one predrilled hole and just drilled another. Mounted the air tank on the right crossmember behind the bumper. I removed the bracket from the compressor and clamped it on the right crossmember just below the air tank, used two radiator hose clamps and I put a piece of cut rubber hose under it for vibration.
