Description
Performance Exhaust Upgrade. The AFE ATLAS 4-Inch DPF-Back Dual Exhaust System with Black Tips is designed to boost exhaust flow for your diesel truck. This system transforms a single exhaust into an aggressive dual setup, improving horsepower, torque, and reducing exhaust gas temperatures for enhanced engine performance and reliability.
Construction and Appearance. Crafted from 4-inch mandrel-bent aluminized steel tubing, this exhaust ensures maximum flow with smooth transition bends to minimize turbulence. It features dual 6-inch high-temperature powder-coated black stainless steel tips with laser-cut logo plates and a drain port to prevent rust and corrosion, combining durability and aggressive styling.
Installation. The system installs easily using all factory mounting points and includes OE-style bayonet hangers and a bolt-on bracket for precise alignment. No drilling or modification is required, making for a quick and hassle-free upgrade.
Application. Fits 2011-2016 6.6L Duramax Sierra 2500 HD diesel trucks.
