i have a set of Hadley Bully Air horns that i had on my ram. I'm gonna be putting them on my nitro once i get it this weekend. They are compact and louder than my neighboors train horn lol and he's pushing just over 152 db. They are meant for eighteen wheelers. I'll post pics and a vid once i install them.
Here a pic of when i had it in the ram:
