Engineered to perform in the most extreme environments, aFe Atlas exhaust systems are constructed from mandrel-bent aluminized steel tubing with high-quality band clamps and OE-style bayonet hangers. Where applicable, free-flowing aluminized steel mufflers are used to absorb high-pitch tones producing a powerful sound and unleashing more horsepower and torque out of your rig. Atlas systems use factory mounting locations to provide a quick, hassle-free installation. Some of these diesel exhausts are wrinkle-black powdercoated or polished 304 stainless steel tips with laser-cut stainless steel aFe badges. aFe Atlas exhaust systems are a tremendous combination of performance, fit, and value.
