Description
The AFE49-44007NM MACH Force XP 5" Downpipe-Back Exhaust System for your 01-07 GM 6.6L Duramax is engineered to perform in the most extreme environments. Constructed from 5" mandrel bent 409 stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. This system is available in 5" turbo-back without muffler. All MACH Force exhaust systems come with all the necessary hardware for a clean and simple installation.
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 muffler eliminator pipe is used for 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 5"" mandrel bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

I went back and forth on whether or not to do a 4" or 5", and am I glad I went with this 5". It sounds amazing, was a simple install and looks great! High quality band clamps and a simple install made this a no brainer. Not too loud, unless you want it to be, no drone and excellent V8 rumble. I also like the turn on the tailpipe giving it a little bit of an older Chevy look with the straighter outlet. 06 LBZ CCSB
