Looking to improve your 6.6L Duramax’s sound and performance? The MBRP Armor Lite DPF-Back exhaust helps your truck breathe easier, delivering smoother acceleration, stronger torque, and a more responsive throttle. By replacing the restrictive factory system, it reduces backpressure, keeps turbo spool quick, and gives your Duramax a refined, deep exhaust tone you can enjoy every day, whether you’re towing, hauling, or hitting the highway.
Featuring 4-inch tubing and a CARB-approved downpipe, the Armor Lite ensures consistent airflow and linear power delivery. The Tour Profile keeps the exhaust note controlled and balanced, giving you a satisfying, aggressive sound without being overwhelming for daily driving.
Built from heavy-duty aluminized steel with CNC-formed bends and MIG-welded joints, the system is designed for long-lasting durability. Every pipe, hanger, and clamp is engineered for optimal gas velocity, corrosion resistance, and reliable performance under both everyday driving and heavy-duty towing conditions, mile after mile.
