Description
ATLAS 4” Aluminized Steel DPF-Back Exhaust System – Ford Super Duty 6.7L Power Stroke (2011–2014)
Enhance the performance, sound, and appearance of your 6.7L Power Stroke with the ATLAS 4” DPF-Back Exhaust System by aFe POWER. Designed using advanced airflow engineering and validated through in-house dyno testing, this system delivers proven gains of +8 horsepower and +11 lb-ft of torque over the factory exhaust while maintaining an OE-quality fit and finish.
Constructed from 4” mandrel-bent aluminized steel tubing, the ATLAS system maximizes exhaust flow while reducing restriction and turbulence. Smooth transition bends, a mitered merge collector, and intercooling tailpipes work together to improve scavenging efficiency, increase power output, and help lower exhaust gas temperatures (EGTs).
