I rarely use the horn on the car, and when I do it's usually to say hello. For correct use I usually reserve it for complete a$$holes who deserve to be driven off the road. Problem is that the FTO horn is so pathetic, I am nearly embarassed to use it. Someone carves you up on the road, you site on the horn to advise them that you are unhappy, and then they just laugh at you

The child in me wants a fog (truck type) gas horn, or possibly a Dukes of Hazard horn, for when I'm being chased by the local constabulary.
But I'd settle for something with a bit more base, a bit deeper, type horn used on VW's or BMW's. Question is car I just pick up any old horn in a scrap yard, and fit it to the car?
