Description
Large Bore-HD 5” 409 Stainless Steel DPF-Back Exhaust System – LMM Duramax
Upgrade your diesel truck’s performance and reliability with the Large Bore-HD 5” DPF-Back Exhaust System from aFe POWER, specifically engineered for 2007–2010 GM HD trucks equipped with the LMM Duramax. This system is designed to deliver maximum exhaust flow, reduced exhaust gas temperatures (EGTs), and long-lasting durability, all while maintaining a precise OE-style fit.
Constructed from 5-inch mandrel-bent 409 stainless steel tubing, this exhaust system offers excellent corrosion resistance and structural strength for demanding diesel applications. The smooth-radius mandrel bends minimize turbulence, allowing exhaust gases to exit efficiently—resulting in improved horsepower, torque, and throttle response.
The DPF-back configuration ensures emissions components remain intact while optimizing post-DPF airflow. Installation is fast and straightforward, utilizing factory mounting locations, OE-style bayonet hangers, and high-quality band clamps to provide a secure, leak-free fit with no permanent modifications required.
