Description
ATLAS 4” Aluminized Steel DPF-Back Exhaust System with Dual Polished Tips – Ford Super Duty 6.7L Power Stroke (2011–2014)
Upgrade your 6.7L Power Stroke with the ATLAS 4” DPF-Back Exhaust System by aFe POWER, engineered to deliver measurable performance gains, improved exhaust flow, and aggressive styling while maintaining OE-quality fitment. Verified through in-house dyno testing, this system produces gains of +8 horsepower and +11 lb-ft of torque over the factory exhaust.
The ATLAS exhaust is constructed from 4” mandrel-bent aluminized steel tubing, ensuring maximum airflow and reduced backpressure. Smooth transition bends and a mitered merge collector minimize turbulence and eliminate dead space, resulting in improved scavenging efficiency, increased power output, and reduced exhaust gas temperatures (EGTs). To further enhance thermal performance, the system incorporates intercooling tailpipes, helping to lower EGTs at the tailpipe exit.
