ATLAS 4" Down-Pipe Back Aluminized Steel Exhaust (No Muffler) Race System 2011-2015 GM 6.6L Duramax
The new ATLAS exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4” 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 360º sealing area. A 12" free-flowing straight-through designed muffler is used to produce a deep, powerful sound. Systems are available in 4” down-pipe back with muffler. ATLAS exhaust systems are the perfect combination of performance, fit and value.
