Well one of my riding buds (JohnnyBoy) got this on his bike and all I can say is WOW! 118 DB and it's only about $60 with shipping off ebay. The compressor is built in and it is nice shiny chrome. It has to be wired in with it's relay in it's own circuit off the battery, but this is going to be my next mod. LOUD horns come in real handy in big city traffic.
I have mine for 2 seasons. Loud & nasty.....The Stebel, Mini Beast, Mini Beast II & the Wolo Bad Boys are all the same horn. I have a MB II coming for the Heritage.
LOUD as hell. I honky JohnnyBoys at the coffe shop preride this morning and everyone was looking around for the big rig. LOUDER is better for horns on motorcycles. I ran a WOLO dual trumpet on another bike I had a few years ago. It got the job done well too.
