Conçu pour être facile à installer, ce kit tout-en-un permet une installation sans difficulté et transforme la signature sonore de votre véhicule en seulement quelques heures.
(Remarque : les compresseurs d'air montés sur réservoir ne sont pas totalement étanches. Pour cette raison, nous recommandons d'installer le système réservoir/compresseur en position verticale, dans un espace fermé à l'abri de l'humidité, de la saleté, des débris, etc. Le non-respect de ces instructions d'installation annulera la garantie)
Le détachement du compresseur du réservoir annulera la garantie de ce kit. Si vous avez besoin d'une solution avec un compresseur séparé, consultez nos modèles 232 et supérieurs.

A 3-chime metal train horn tuned for the deep, layered locomotive sound the Outlaw is known for, in a shell that fits where the full-size kit will not.
A complete onboard air source, compressor and tank both, in a footprint built for tight installs. It makes its own air and refills between honks.
The electric air valve comes pre-installed and the air source ships pre-assembled. Everything else needed for the install is in the box.
One recording of the Mini Outlaw 3-chime horn at full pressure. No editing.
Phone speakers undersell it. Earplugs ship in the box for a reason.
Same Mini Outlaw horn on both kits, weather resistant either way. The air system decides how long you can honk and whether the air source is sealed against the weather.

The M3 compressor and tank combo operates at 120 PSI, and the 3-liter tank provides 2 to 3 seconds of honk time. It refills from 90-120 PSI in about 35 seconds. The most affordable way to run the Mini Outlaw, backed by a 2-year warranty.

The 127H air source operates at 120 PSI, and the 1.5-gallon 4-port tank provides 4 to 5 seconds of honk time. It refills from 90-120 PSI in about 35 seconds. The air source is sealed against the elements, for builds that live outdoors.
The finish is the only difference. Same 3-chime horn, same air system, same roar.


Each kit ships complete and ready to install. The horn is the same; the air system and its plumbing are what change.
