The aFe Large Bore HD 5-inch DPF-back exhaust system is engineered for optimal performance and durability on 2017 Chevrolet Silverado and GMC Sierra 2500HD/3500HD models equipped with the V8-6.6L Duramax L5P engine. Crafted from high-quality 409 stainless steel, this mandrel-bent exhaust features smooth transition bends that promote low turbulence, resulting in increased horsepower and torque while reducing exhaust gas temperatures for improved engine efficiency. The system is designed for straightforward installation, utilizing factory mounting points to ensure a stable and secure fit without the need for modifications.
The included high-quality band clamps provide a leak-free seal, ensuring a complete 360-degree sealing surface for optimal exhaust flow. OE-style bayonet hangers are used to maintain proper pipe positioning during high vibration and heat conditions. The bayonet tips secure the hanger bushings in place, preserving the OE-style fit over time, even under demanding driving conditions.
Finishing the system is a 6-inch diameter, black stainless steel slash cut tip with intercooling vents, engineered to lower tailpipe temperatures and enhance exhaust flow. The laser-cut aFe Power logo adds an aggressive aesthetic touch, complementing the performance upgrades. This system is built to withstand the harsh conditions faced by diesel trucks and provides a significant upgrade in exhaust flow, sound, and appearance.
Please note that this exhaust system is not CARB approved and is intended for off-road use only. It meets Prop 65 requirements for material safety and is designed specifically for 2017 GM Duramax V8-6.6L (L5P) diesel trucks, delivering reliable performance and a commanding sound profile.
