Product Description

The aFe 49-04041 ATLAS 5" DPF-Back Exhaust System is engineered as a direct replacement for select 2011-2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L LML Duramax turbodiesel engine. Constructed from robust 5" mandrel-bent aluminized steel tubing, this exhaust system improves exhaust flow and reduces backpressure compared to the stock DPF-back design, helping unlock additional horsepower and torque while delivering a more commanding exhaust note.

This ATLAS system uses factory mounting points, OE-style band clamps, and bayonet hangers to ensure a hassle-free, bolt-on installation without cutting or welding. The aluminized steel construction offers long-lasting corrosion resistance, and the 2-year limited warranty provides added peace of mind. Performance-minded owners who want improved flow and a more aggressive sound will appreciate the balance of quality and value this system delivers.
