Mini Outlaw Train Horn Kit
WHO SAYS YOU GOTTA BE BIG TO BE AN OUTLAW?
Where space is a premium but compromising on the authentic train horn tone is not an option, meet the Mini Outlaw 3-liter horn kit. Expertly engineered to deliver the distinctive 3-chime metal train horn tone in a compact form, this kit proves that big sounds can come from small packages.
Powered by the M3 3-Liter air source unit, the Mini Outlaw guarantees a consistent, unmistakable tone, ensuring you're not just heard, but remembered. Designed for ease, this all-in-one kit ensures a seamless installation, transforming your vehicle's auditory signature in just a few hours.
- Compact Yet Commanding: Made for limited spaces, this 3-chime metal train horn keeps the signature Outlaw sound in a condensed design.
- Surprisingly Agile: The M3 3-Liter air source, though compact, grants 2-3 seconds of honk time, recovering in only 35 seconds.
- Hassle-Free Installation: With a high-flow 1/4" valve that's already in place and a pre-assembled air source unit, this complete kit simplifies setup, getting you on the road faster.
- Optimized Air System: Complete with a 110 PSI air system, the Mini Outlaw ensures you have the resources to announce your arrival whenever you need to.
(Note: Tank-mounted air compressors are not fully sealed. For this reason, we recommend the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc... Failure to mount this product as directed will void the warranty)
**Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models. **
