The AFE 49-42009-1 MACH Force XP 4" Turbo-Back Race Exhaust System for your 2007.5-2012 Dodge 6.7L Cummins is engineered to perform in the most grueling competition environments. This race exhaust system is built from mandrel bent 4" stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT’s. MACH Force XP exhaust systems are the perfect combination of performance, fit and value.

Installation is a Snap:
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. Muffler delete-pipe is also included for those who prefer a true race-inspired sound and maximum flow.

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 4" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT’s.


  • 4" Stainless Steel Construction
  • Includes Muffler & Muffler Delete Pipe

Warning: This free-flow race exhaust system requires the use of an aftermarket performance programmer with off-road tuning.

Sounds great, Install sucks..

I went with the full delete pipe and it sounds great! They claim it fits all models except cab and chassis but that is a lie. I have a 2011 Ram 2500 extended crew cab and didn't fit. Instructions are misleading in multiple ways, I had to customize one of the mid pipes and cut it to make it all fit and it is still slightly off underneath but not noticeable from the outside except when you put the tip on it sticks out 6" from the fender, which I also had to cut and modify. Tip that comes with it is to small for my liking but overall this product would have gotten more stars if it was actually a perfect fit like they claim and I wouldn't have had to cut multiple pieces to make it fit. Overall product sounds great and when I get a better tip it will look better! As always thanks XDP for the best prices and fast shipping!
Very nice exhaust.

Easy install (although directions are misleading on picture) awesome results. I used muffler and sound is very reasonable inside cab (not much different from stock) and other tell me it sounds great outside truck.
