Loud enough to convince other drivers that there's a derailed freight train barreling down on them. Don't press the horn button in the garage, it hurts! At 139dB it can be heard for almost 3 city blocks!

Includes a single M8 mounting bolt and nut, as well as a relay for providing a direct, high current attachment to the motorcycle's battery.
Per the manufacturer, this horn should be mounted so that the cylinder is vertical (with the horn facing down). There should be no more than a 15 degree variance from the vertical position. If it is not mounted per these specifications, then the horn may cease to function after a period of time.
If you own a 2003-2005 Harley Davidson motorcycle and horn relays are repeatedly failing, please visit your local dealership to upgrade your horn button under the Harley recall.
No wires, fuses, or bike-specific mounting brackets are included.
You may want to purchase the pre-made wiring kit & brackets.
Keep this in mind: sound energy doubles for every 3 points you go up in the decibel scale. It means that the Stebel Nautilus horn, which produces 139 dB of sound, puts out a LOT more sound than these popular horns:
- 800% of the sound energy of the more expensive 130dB FIAMM Freeway Blaster;
- 600% louder than the $140, 130 dB Pro Pad Mini Beast horn;
- 650% louder than the $179, 128dB Rivco dual trumpet horn.
You will not be disappointed - just make sure you wire the included relay properly, as replacement horns used without a relay don't get enough electrical current to be fully effective.

I installed it in my Miata MX-5 3 years ago. Love it; gets you the respect that the scooter-like OEM horn does not. Still working fine...
Great horn. Due to improper mounting, I lost the first one. My bad! It’s good enough to buy a second one. It’s loud enough to scare my wife in the garage
Aside from the birthday candle headlight I replaced, this air-horn has been one of the best upgrades. The stock meep meep was embarrassingly useless. At 139 db this thing blasts and turns heads for blocks. I rigged up a easy and simple custom bracket and it blends and tucks right in.
Deserving people/idiots have jumped out of their seats which eases my extreme annoyance by providing me a few laughs. Tooted it for my wife...she jerked, frowned and walked away. HAHA. Buy it.
