aFe POWER Large Bore 4in 409 SS Exhaust Down Pipe Back 2017 Ford Diesel Trucks V8 6.7L (td)

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. Includes additional hanger bracket for driver-side mount. No cutting required.

5" Black Intercooled Tips:
Finishing off the exhaust is a set of dual-side exit 5" stainless steel intercooled clamp-on tips with a black finish. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.
