I have an 2004 duramax, and I am looking for an underhood airhorn kit with compressor, loud, did I say loud.... I drive a truck at work with big flashing light and I love that airhorn, can anyone help?

We installed one in a crane last year, not sure of the manufacturer, got it through Truckparts, kinda pricey $200 +. I'll check next time I'm at the shop, P.M. me if I forget!
Here's one place, the one we used was nicer with the compressor mounted on a small pancake tank.

I have Hadley Ambassadors on my truck. . . They are plenty loud, and the kit came with compressor, tank, and accessory hose. I mounted my horns in the space in the bed in front of the right rear wheel. Go to www.campingworld.com and search for Hadley, you will find the Ambassador kit. . . they come in either anodized or chrome. . . around 300 for the kit.

Checked at the shop today, compressor kit and horns actually came from NAPA P/N 827-8032 for the compressor kit, and P/N 730-1330 for one of the many air horns listed. These parts are found in the "parts and supplies" catalogue page 485 in the 2003 edition. Hope this helps.
