I had one of those Stebal Nautilus horns on my old 250 and it was one of those fog horn type ones but it runs off your 12 volts battery, not air compressors like most. it was fu**ing loud
. I beep me mate in traffic once before i told him i got it he though it was the lorry beside him so he give him the fingers. So funny
. Only thing is it is quite big, but i see they have brought out a compact version, dont know if it would fit into the oe horns place, but would be worth trying as it is LOUD AS F**K
