Chris S. went all out with his 2017 GMC Sierra 1500, installing our Shocker S6 544K Nightmare Edition Train Horn Kit, the loudest setup we offer. But Chris didn’t stop at volume, he added both a 220 PSI Digital Air Pressure Gauge and an Electric Drain Valve Kit to make sure his system runs clean and strong at all times.
With six tuned bells under the hood and advanced components for pressure monitoring and auto-draining, Chris’s Sierra isn’t just loud, it’s dialed in for performance, reliability, and total dominance.
If you’re looking to install a horn system that screams performance and turns heads every mile of the way, Chris's build is the ultimate inspiration.
