IS THIS A SIN ??

I had the same problem, and bought a fiamm 'freeway blaster' (its a trumpet /
air horn type). You should be able to find them an any local autoparts store.
It came with the hardware to mount in the same location as the stock horn,
and wasn't too big (5amps) for the stock horn relay. Very easy to wire up and
sounds pretty good, significantly louder than the stock one.
