The AFE 49-03066-P ATLAS 4" Downpipe-Back Dual Race Exhaust System for your 2011-2016 Ford Super Duty is constructed from 4" mandrel-bent aluminized steel tubing for maximum flow. This dual system includes two dual side exits finished off with AFE-Power 6" polished stainless steel clamp-on tips with a black laser-cut stainless steel AFE power plate. Designed with oe-style bayonet hangers and using high-quality band clamps, this system installs easily with top quality hardware in your factory locations.

Flow and Performance:

This ATLAS Down-pipe exhaust system is 100% hand MIG-welded and Constructed from 4" mandrel-bent aluminized steel tubing  for maximum flow. The smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGTs. A mitered merge collector is also incorporated to eliminate dead space that can cause turbulence and hinder flow.

Aggressive Sound:
A free-flowing aluminized 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 Polished Clamp-On Tips:
Finishing off the exhaust are dual side exit 6" stainless steel clamp-on tips with a high luster polished 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.
