For a kick, I installed a cheap set of JC Whitney air horns(for $28) on my wife's Escort. There add claimed 130 decibels loud. These air horns were definetly loud. They were the loudest horns I've experienced and worked great for scaring deer off the roadway. The problem is they just do not last. Bought two sets, and the air pumps crap out in about two months. After taking a deffective pump appart, I saw why these pumps fail. They are cheap pieces of crap! Just plastic and pot metal, and not made to last. Anybody know of a quality loud airhorn? Ranger Jim
