Stainless Steel Exhaust Upgrade for 6.7L Powerstroke

Enhance the performance, durability, and sound of your 2011–2014 F250/F350 6.7L Powerstroke with the Diamond Eye 4-inch DPF Back Stainless Steel Single Exit Exhaust. Designed for drivers who demand the ultimate in reliability and style, this exhaust system delivers a simple and effective upgrade enhances your truck’s character. Crafted entirely from high-quality stainless steel, this system is built to last. Stainless steel offers superior resistance to rust and corrosion, ensuring your exhaust maintains its performance and appearance no matter what Mother Nature throws your way. The included muffler is also made from premium stainless steel and features a perforated core which works to optimize airflow and efficiency each time you get behind the wheel. Unlike stock mufflers that can typically sound flat, this muffler strikes a perfect balance—adding a bold exhaust note without being overly aggressive. It also minimizes drone, making long drives more comfortable whether you're towing, hauling, or commuting.

Delivers Impressive Performance Gains

Another standout feature of this exhaust is the 4-inch mandrel-bent tubing eliminates the restrictive bends found in stock systems, allowing for smoother, unrestricted exhaust flow. This improvement lowers exhaust gas temperatures (EGTs), helps increase fuel economy, and provides slight gains in both horsepower and torque—perfect for heavy-duty tasks or everyday driving. What's more, the polished exhaust tip adds a touch of sophistication, giving your truck a clean exterior look. Its classic design complements the single exit configuration, which is both functional and stylish for the rear-end of your Super Duty. The overall aesthetic is subtle yet impactful, allowing your truck to stand out without looking overdone.
