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.

Installation is a Snap:
ATLAS exhaust systems utilized 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 a hassle-free installation.

Leak-Free Seal:
High quality OE-style flange and band clamps are used for a complete 360 degree sealing surface.

Aggressive Sound:
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.

OE Fitment:
OE-style hangers with bayonet tip are used to maintain a stable pipe location during high vibration and high heat conditions.

Flow and Performance:
ATLAS exhaust systems are constructed of 4" mandrel bent aluminized steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

Polished Tip:
Finishing off the exhaust is a high luster, polished 304 stainless steel exhaust tip. This tip features an aFe Power logo laser etched onto the top of the tip. A drain port on the bottom to keep rust and corrosion away.
