The Mach FORCE XP exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 5"" 409 stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGTs. Systems are 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 mandrel bent 5"" 409 stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs.

Most Popular Questions

Do I need the bungs and will this work for a 4 door dually 8ft bed?
View Staff Answer 
Our XDP fuel additive will restore/increase horsepower and help lower your diesel emissions. I believe your vehicle may actually have an internal issue you may want to have looked over by a professional mechanic. Black smoke is often related to an imbalance in your air/fuel ratio. Either your fuel system is delivering too much fuel or the turbos not delivering enough clean air.

Exhaust bungs may be required depending on the emissions delete tuning you plan on running with the “race” exhaust system. (If they are not required, then the bungs are personal preference) This exhaust system works on all cab and bed configurations.
