The AFE 49-13022 LARGE Bore HD 4" Downpipe-Back Race Exhaust System for your 2008-2010 Ford 6.4L Powerstroke is engineering to perform in the most extreme environments. Constructed from mandrel bent, T409 stainless steel tubing for maximum flow, this system is designed to increase horsepower, increase torque and lower EGT's.
Installation is a Snap:
All systems use factory mounting locations providing stability and hassle-free installation.
High quality OE style flange and band clamps are used for a complete 360 degree sealing surface.
A free-flowing 24" 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 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:
LARGE Bore HD exhaust systems are constructed of 4" mandrel bent 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.
