Description

Maximize power and flow in your 2011-2015 GM 6.6L Duramax LML with the AFE 49-04035-1 ATLAS 5" Downpipe-Back Race Exhaust System. Constructed from 5" mandrel-bent aluminized steel tubing, this kit uses high quality band clamps, and OE-style bayonet hangers for an easy, bolt-on installation.

Simple Installation
All systems use factory mounting locations providing stability and hassle-free installation.

Leak-Free Seal
High quality band clamps are included for a complete 360 degree sealing surface.

OE Fit
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.

Flow and Performance
This ATLAS exhaust system is constructed of 5" mandrel-bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

High Flow Aluminized Muffler
This aluminized steel performance muffler is designed to provide a deep, throaty, powerful sound on acceleration, but maintain a smooth sound at idle. This muffler is constructed of aluminized steel and uses a straight through perforated core with heat resistant packing to reduce backpressure and maximize exhaust flow. You will see increased performance and improved throttle response over the factory exhaust. Also featuring a stamped aFe POWER logo for an aggressive style. Muffler Specifications: 5" Center Inlet /Outlet, 7" Round x 24" L Body Diameter.
