aFe POWER Large Bore-HD 4" 409 Stainless Steel DPF-Back Exhaust System w/ Polished Tip
Fits 2018–2020 Ford F-150 3.0L Power Stroke Diesel
Is your stock exhaust too quiet? The aFe POWER Large Bore-HD DPF-Back Exhaust System is engineered to wake up the sound of your 2018–2020 Ford F-150 3.0L Power Stroke while maintaining a refined, daily-drivable tone. This system features large-diameter 4" tubing and eliminates the factory muffler, significantly improving exhaust sound and flow without compromising fitment or emissions components.
Built from mandrel-bent 4" 409 stainless steel, the Large Bore-HD system maximizes airflow and durability. Smooth, high-radius bends reduce turbulence and backpressure, promoting efficient exhaust evacuation and a clean, smooth exhaust note. Installation is straightforward and hassle-free, utilizing factory mounting locations and OE-style bayonet hangers—no cutting or modification to stock components required.
The system is finished with a 5" polished intercooled clamp-on exhaust tip, designed to help reduce exhaust gas temperatures at the tailpipe while delivering a bold, premium appearance at the rear of your truck. Like all aFe exhausts, it’s engineered and manufactured in Corona, California for proven quality and fit.
