Looking to add 40% more airflow to your 2.8L Duramax, resulting in increased power and efficiency? Well, AFE’s ATLAS 3.5” Aluminized DPF-Back Exhaust system offers just that, and more. Looking for a simple installation? This system uses factory mounting locations providing stability and hassle-free installation. On top of that, OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.
