Ok, you got me to bite... While I lean toward being sort of a purist, I couldn't help myself installing a set of Fiamm Air Horns years ago, very similar to my old F-308. 795 & 840 Hz are the magical blend of tone frequencies that Italian cars are known for and my horns don't disappoint. Loud and just a bit obnoxious is just the ticket!
And, yes, I still have the correct horns boxed up in my basement.
