I have a semi-truck air horn set I picked up at an auction for $5 mounted in the engine compartment. The operating valve is connected to the throttle knob. I also had a spare aircraft oxygen tank I mounted under the bed and fill it occasionally with air from the shop.
FWIW the stock horns on my 13 Charger are LOUD and should be readily available. The car is insulated enough that they're not overly loud inside the car. I was shocked at how loud they are when I heard them outside the car.

These are six volt horns that were disconnected when a previous owner converted to 12 volt. I recently put these in series to use with the 12 volt system and they work nicely, being a high and low pair. They do get people’s attention. Thought viewers might enjoy the promotional literature that I came across. Trumpet horns are cut off by the bad photographer. Ricster
I have a horn from a chevy Trailblazer on my truck. Went to the junkyard, found a trailblazer the horn is not hard to get to, consists of two horns on one bracket. One 10mm. bolt and a snip of the wire and off you go. Why a Trailblazer you ask? A neighbor past one day and blew the horn, That was pretty loud, think I'm gonna get one of those. So I did. It bolted in place of the horn that was on the truck before.
