This guy took a brand new 2015 Silverado 1500 and added twin turbos to it but…he left everything, including the exhaust, 100% stock. At start up and idle, it sounds just like a stock truck, but as soon as those turbos light up, it’s a hell raising, tire slaying BEAST. He took the brand new Silverado in for a service check because it was making a weird whistle sound. The service department was shocked when he stepped on the gas for the first time. He even showed them a head jerking 4wd launch. Enjoy!
