Being somewhat disappointed by the standard horns on The Princess, I was looking for a convenient replacement setup. Personally, I like air horns, but there isn't really sufficient space to fit a standard air horn compressor and horns. A colleague suggested a Stebel Nautilus Compact so I bought one but when it arrived it seemed altogether too small to be of much use. However, I fitted it temporarily to test. My god, I thought the Titanic had returned. The darned thing scared the bejabers out of me. Not that I'm boy racer you understand but the OEM horns just do not match the magisterial presence of the car. Now even those spotty faced erks (like my grandson) will hear The Princess even above the racket their stereos make.
