aFe MACHForce XP Exhaust Aluminized Dual Split DPF Back 11-15 GM Diesel Truck V8-6.6L (td) (pol tip)

Upgrade your LML Duramax truck with the aFe POWER ATLAS 4” Dual DPF-Back Exhaust System, engineered for 2011–2016 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks with the 6.6L LML Duramax engine. Designed for performance, durability, and aggressive styling, this system converts your standard single exhaust into a powerful dual exhaust setup. Constructed from 4” mandrel-bent aluminized steel tubing, this exhaust system ensures maximum flow while maintaining durability and corrosion resistance. Smooth transitions and precise bends reduce turbulence, increasing horsepower, torque, and reducing exhaust gas temperatures (EGTs). Installation is quick and effortless, utilizing all factory mounting points and OE-style bayonet hangers. A bolt-on bracket supports the driver-side tailpipe, ensuring stability without any modifications. This system is designed to fit without relocating the spare tire, maintaining convenience and factory fit. The ATLAS 4” exhaust is finished with dual massive 6” polished 304 stainless steel slash-cut tips, each featuring a drain port to prevent corrosion and a laser-cut aFe POWER logo plate for a bold, aggressive look.
