Derek's 2008 GMC Sierra 2500HD is a testament to extraordinary auditory prowess, thanks to the installation of both the Nathan Airchime K3 and Shocker XL train horns. These horns, known for their unrivaled loudness and authentic locomotive sound, come together to create a sonic force that reverberates for miles. The meticulous installation ensures that despite the horns' imposing sound, the aesthetic integrity of the GMC remains untouched, showcasing a seamless fusion of form and function.
Powering this auditory marvel is the HornAir 544K onboard air system. Housed securely, this system includes a 5-gallon air tank paired with a constant duty air compressor, ensuring Derek has an ample air supply to honk to his heart's content. The air system not only propels the horns but also doubles as a practical utility for airing up tires or running small air tools, adding a layer of practicality to its audacious persona. This installation on Derek's GMC Sierra embodies the essence of customization, blending visual appeal with auditory dominance, making his presence known whether coming or going.
