aFe Power Large Bore HD 4" Stainless DPF-Back w/Black Tips | 2017-2018 Ford Powerstroke 6.7L

Flow and Performance

This Large Bore-HD exhaust system is 100% hand MIG-welded and Constructed from 4" mandrel-bent 409 stainless steel tubing for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's. A mitered merge collector is also incorporated to eliminate dead space that can cause turbulence and hinder flow.

Perfect Fit

This system uses all factory mounting locations providing stability. Includes OE-style bayonet hangers which 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. Some cutting maybe required during install. Please see instruction sheet for Cab configuration for further details.

5" Angle-Cut Rolled Edge Matte Black Intercooled Clamp-On Tips

Finishing off the exhaust are dual side exit 5" stainless steel intercooled clamp-on tips with a matte black finish. A unique laser-cut aFe Power logo black powder-coated plate is riveted on for an aggressive style.
