AFE 49-02003 ATLAS 4" Turbo-Back Exhaust System
|The AFE 49-02003 ATLAS 4" Turbo-Back Exhaust System for your 2004.5-2009 Dodge 5.9L/6.7L Cummins is engineered to perform in the most extreme environments. This system is constructed from precision, 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 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 4” turbo back or 4” down pipe back with or without muffler. ATLAS exhaust systems are the perfect combination of performance, fit and value
Installation is a Snap:
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 360º sealing surface. Standard U-bolt clamps used by other systems only seal at the bottom and top of the tube allowing leak paths.
A free-flowing 12" wide muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque out of your rig.
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:
ATLAS exhaust systems are constructed of precision, mandrel bent 4" aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.

I went with the muffler option because I think a straight piped 5.9 just doesn't sound good under throttle. This system sounds great. Not much louder than stock at idle, much deeper, throatier tone. Once you put the pedal down this pipe will turn heads without that annoying straight pipe sound. Definitely recommend
