Description
ATLAS 5 IN Aluminized Steel DPF-Back Exhaust System
For 2007–2010 GM Silverado & Sierra 2500HD/3500HD Duramax 6.6L
Upgrade the exhaust performance of your LMM Duramax–powered GM truck with the aFe POWER ATLAS 5" DPF-Back Exhaust System—engineered to deliver improved exhaust flow, reduced exhaust gas temperatures (EGTs), and long-lasting durability at an exceptional value.
Constructed from 5-inch mandrel-bent aluminized steel tubing, this DPF-back exhaust system maximizes airflow while maintaining excellent corrosion resistance for daily driving and towing applications. Smooth transition bends reduce turbulence, helping improve horsepower and torque while supporting lower EGTs under load.
Optimized Flow & Performance
The large-diameter 5" tubing allows exhaust gases to exit efficiently, improving overall engine breathing. This design enhances throttle response and supports better performance during towing, hauling, and highway driving.
OE-Style Fit & Hassle-Free Installation
The ATLAS exhaust system is designed to bolt directly to factory mounting locations using OE-style bayonet hangers for a precise, stable fit. High-quality OE-style flanges and band clamps provide a full 360-degree sealing surface to eliminate leaks and ensure long-term reliability. No cutting or modifications are required, making installation quick and straightforward.
