Has anyone installed one of these horns on their motorcycle? I've heard that it will fit under the stock Harley horn cover and is louder than the stock horn. It's advertised for sale on Amazon as; FIAMM 72112 Freeway Blaster Horn Price: $15.91 Features steel housing and plastic projector, can be mounted singly or as duals, 130 dB Copper wire coil motor, available with universal mounting bracket or right angle bracket Corrosion resistant finish So, this horn is one that I read was a recommended replacement for the stock HD horn and at a good price. That is why I am inquiring. Does anyone have an idea how loud the stock horn is? Is 130db especially loud when it comes to bike horns? Anyone....class?
