Interested in a new exhaust system for your 6.7L Cummins? Check out the MACH Force XP DPF-Back exhaust system by aFe.

This system is constructed from 5" mandrel-bent 409 stainless steel tubing and uses high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations to provide a quick, hassle-free installation. The Atlas series kits are available with three different tip options. You can opt to have no tip, a 6" polished 304 stainless steel tip, or a massive 7" wrinkle-black powdercoated 304 stainless steel tip. MACH Force XP exhaust systems are the perfect combination of performance, fit and value.

Simple Installation: 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.

OE 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: This MACH Force XP exhaust system is constructed of 5" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

Polished Tip Option: Finishing off the exhaust is a high luster, polished 304 stainless steel slash-cut exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away.

Black Tip Option: Finishing off the exhaust is a powder-coated black 304 stainless steel exhaust tip. This tip features a drain port on the bottom to keep rust and corrosion away. A unique stainless steel laser-cut aFe Power logo plate is riveted on for an aggressive style.

All aFe exhaust systems are engineered and manufactured in their Corona, California manufacturing facility.
