The 2011-2022 Ford 6.7 Powerstroke is a well-regarded diesel engine found in the F250 and F350 SuperDuty trucks. Upgrading to a 5-inch exhaust system can enhance both performance and sound. Here’s a look at the features, benefits, and things to consider when upgrading to a 5″ exhaust for your 6.7 Powerstroke.

A 5-inch exhaust significantly improves exhaust flow, which can enhance engine performance. By lowering backpressure, the turbocharger can spool more effectively, resulting in increased horsepower and torque. The larger diameter allows exhaust gases to exit more quickly, which is especially advantageous for trucks with higher boost levels or aftermarket tuning. For heavy-duty applications like towing or hauling, a 5-inch exhaust system can help keep exhaust gas temperatures (EGTs) lower, boosting overall performance and durability.

The 5″ exhaust gives the 6.7 Powerstroke a deep, aggressive tone compared to the factory exhaust system. It amplifies the turbo whistle and delivers a robust exhaust note that diesel fans appreciate. Keep in mind that the sound will change depending on whether you choose to keep or remove the muffler or resonator. Without these components, the truck will produce a much louder and more raw exhaust sound.

5-inch exhaust systems are usually constructed from high-quality aluminized steel or stainless steel. Stainless steel is more resistant to corrosion and rust, particularly in areas with severe weather or road salt, making it a popular choice for longevity. Mandrel-bent tubing is commonly used to ensure smooth bends without reducing the diameter, allowing for optimal exhaust flow throughout the system.

The 5″ exhaust kits for the 6.7 Powerstroke are designed as bolt-on systems, meaning they can be installed without significant modifications. Most kits come with all the necessary clamps, hangers, and hardware. Some kits are designed specifically for certain applications.
