The AFE 49-03004 ATLAS 4" Downpipe-Back Race Exhaust System for your 2008-2010 Ford 6.4L Powerstroke is engineered to perform in the most extreme environments. This race exhaust system is constructed from precision, mandrel bent 4 aluminized steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. 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. This system comes with your choice of a 12" free-flowing straight-through designed muffler or no-muffler configuration for the most sound. 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.

Leak-Free Seal:
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.

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.

Perfect Fit:
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 EGTs.

Not satisfied!
Location: Kansas
I bought this kit due to the band clamps and oe style hangers. Kit came missing hardware. The middle hanger sat about 4 inches lower than the front/ rear hangers so you have to cut a piece of the hanger out if you want it to not sag. There were bent pipe ends in the box that made the already tight fittings impossible to work with. I have installed multiple mbrp kits on 6.4 Powerstrokes and they were a breeze. This kit is a joke.
