This exhaust system is engineered to unleash an aggressive and deep rumble from your truck by utilizing straight-through muffler technology. It aims to provide maximum power and high performance through efficient exhaust flow, mandrel-bent curves, and a high-flow muffler design, leading to increased horsepower, throttle response, and torque. The system is constructed from lightweight, 18-gauge, mandrel-bent 409 stainless steel for strength, durability, and corrosion resistance. It features a 4-inch, angle-cut, polished 304 stainless steel exhaust tip with laser-etched Hooker Blackheart logos. It's designed for bolt-on installation using factory mounting points with included hardware and moderate mechanical skills. This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.
