aFe ATLAS 5" Exhaust System, Aluminized, DPF Back - NO MUFFLER - 7" Black Tip, 11-14 GM Duramax 6.6L LML - 49-04041-B

The new ATLAS exhaust is engineered to perform in the most extreme environments. This system is constructed from precision, mandrel bent aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. The 2-piece tailpipe and bayonet style hangers provide a hassle-free installation. To provide a leak-free seal, OE style band clamps are used that offer a 360° sealing area vs. cheap U-bolt clamps used in other systems. A 12" free-flowing straight-through designed muffler is used to produce a deep, powerful sound. Systems are available in turbo back or down pipe back with or without muffler. ATLAS exhaust systems are the perfect combination of performance, fit and value. ATLAS exhaust systems utilize a 2-piece tailpipe design for a perfect fit by allowing adjustability at the tailpipe section. All systems use factory mounting locations providing stability and hassle-free installation. High quality OE style band clamps are used for a complete 360° sealing surface. Standard U-bolt clamps used by other systems only seal at the bottom and top of the tube allowing leak paths. OE style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
