The AFE 49-43040 MACH Force XP 5" Down-Pipe Back Race Exhaust System for your 2008-2010 Ford 6.4L Powerstroke is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 5" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. This system is available in 5" down-pipe back with muffler. Mach FORCE XP exhaust systems are the perfect combination of performance, fit and value.

Installation is a Snap:
Mach FORCE XP 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 flange and band clamps are used for a complete 360 degree sealing surface.

Aggressive Sound:
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.

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:
Mach FORCE XP exhaust systems are constructed of 5"" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

I just installed this 5 inch system with the muffler and it sounds GREAT!! I am a novice when it comes to the diesel world and this was a piece of cake to install. The sound is nice and throaty with a nice low base tone to it. I can’t say enough about this AFE system it is great. If you are thinking about buying this thing and are on the fence get it you won’t be disappointed!
