Hi, bmwcliff in western Pa., over the years I have read about folks adding, changing to a louder horn such as a Fiamm. I have an 04 Rockster and would like to change to something much more noticable without being insulting or rude to other riders/drivers. Also, I want something small enough to hide. What model Fiamm would I look for? Also open to other models/manufacturers and just looking for advice/wisdom from others.
