– Sold Out

If you are wanting your horns to be large and loud without breaking the bank, as well as having a fully capable constant-duty onboard air system that can take on almost any pneumatic task you come across, then our Katrina 544K nightmare edition train horn kit is the train horn kit that you need!

Our Katrina train horn unleashes a torrent of massive train horn tone, consisting of 5 large metal horns on a sturdy metal frame, with our 3/8” Solinoid Valve that is pre-plumbed directly into the manifold of the horn. As one of the loudest 5-chime horns that we carry, our Katrina Train Horn is sure to get people’s attention. Sporting a stealthy black finish to match our all-black HornAir 544K onboard air system, our Katrina Train Horn is just as stylish as it is incredibly loud. 

We bundled this tempest of a train horn with our HornAir 544K nightmare edition onboard air system to give your Katrina train horn all the power it needs to be heard from miles away. In addition to giving you 10 seconds of continuous blast time, this kit will also support other onboard air applications such as tire inflation, use of air tools, and load-leveling air suspension. Our 5-gallon black 8 port air tank is powered by a constant duty Viair 444C stealth black air compressor with a 100% duty cycle at 100 PSI, providing workhorse performance while only pulling 20 amps. 

While this kit gives you everything you need to get up and going, make sure to pick up our tire inflation kit, wireless remote, and mounting bracket to get the most out of one of the best train horn kits you can buy.

An increasing number of people are using this for more than just blasting horns! With a system like our Katrina 544 Nightmare Edition Train Horn Kit, you can also use the air supply to:

  • Adjust Tire Pressure

Katrina 544 Nightmare

Great product. Had one issue with threads on a fitting during install. I called Hornblasters and they sent me what I needed and it got to me quick. This is the second Hornblaster set up I have purchased. First one lasted 10 yrs. Only reason for the new one was I upgraded the truck. The Katrina horns are loud and sound like a true locomotive.


Love them

Great instructions kinda hard to follow other than that awesome



It is amazing and I definitely recommend it to anyone wanting horns


Excellent product

Install was easy for me. I had a plan on my vehicle so I ordered what would fit. It was the Katrina horns. I used my Def platform for compressor and tank. Will provide pics soon.
