AFE Power Atlas 4" Aluminized Downpipe Back Exhaust System
49-04003 / 49-04003NM
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 360? 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 and 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 360? sealing surface.
Muffler Option Features Aggressive Sound:
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 mandrel bent 4" aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.
