Making a powerful statement at the 2017 SEMA Show, CaliCustomsOKC’s 2017 Nissan Titan Crew Cab showcased both bold styling and earth-shaking sound. This Titan was outfitted with our Conductor’s Special 544K Nightmare Edition Train Horn Kit, and to push the limits even further, an additional set of Shocker XL Train Horns was added—bringing the total to eight horns.
The installation was carefully designed for maximum sound dispersion, with each horn strategically positioned to harmonize with the Titan’s aggressive exterior. The result is a setup that not only commands visual attention but also dominates acoustically, delivering the full impact of real locomotive power.
The 544K air system, paired with dual sets of Shocker XL horns, ensures long honk durations and fast recovery—making this setup as functional as it is fearsome. This install perfectly blends visual intimidation with acoustic authority, proving that the Nissan Titan is more than just a show truck—it's a sound powerhouse.
