ATLAS 4" Down-Pipe Back Aluminized Steel Exhaust Race System 2007.5-2010 GM 6.6L Duramax
The 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 system is available in a 4" down-pipe back with muffler and is finished off with a polished tip. ATLAS exhaust systems are the perfect combination of performance, fit and value.
A free-flowing 12" x 8" long muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.
