aFe 49-43066-B 2011-2014 Ford Powerstroke 6.7L 4" Downpipe Back Dual Side Exit Exhaust System w/Black Tips Stainless Steel

Flow and Performance:

This ATLAS Down-pipe exhaust system is 100% hand MIG-welded and Constructed from 4" mandrel-bent 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.

Aggressive Sound:

A free-flowing stainless steel 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:

This system uses all factory mounting locations providing stability and hassle-free installation. 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.

6" Angle-Cut Rolled Edge Black Clamp-On Tips:

Finishing off the exhaust are dual side exit 6" stainless steel clamp-on tips with a black finish. A unique laser-cut aFe Power logo plate is riveted on for an aggressive style.

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