Jeremy’s 2016 Toyota Tacoma just got LOUD, thanks to the Conductor's Special 544K Nightmare Edition Train Horn Kit, one of the most powerful setups we offer. This system features the iconic Shocker XL Train Horns, now mounted cleanly in the spare tire location under the bed for a stealthy yet thunderous configuration.
This premium kit isn’t just about sound, it’s about utility. The included HornAir 544K Onboard Air System packs a 5-gallon air tank and a constant duty compressor, delivering 10–12 seconds of horn time and supporting everything from tire inflation to air tools and more.
Jeremy leveled up even further by tuning the system to run at 200 PSI, boosting performance for demanding tasks. To protect the Shocker XL horns, he wisely integrated a high-pressure regulator, capping the horn output at our recommended 150 PSI, the perfect balance of performance and safety.
Whether cruising the streets or prepping for trail work, Jeremy’s Tacoma is now a beast in both sound and function, with a clean, pro-grade install that proves you don’t have to choose between style and substance.
