Aftermarket Exhausts Systems are one of the most popular upgrades for any 2017-2022 Ford 6.7L Powerstroke. Exhaust systems are typically available in stainless or aluminized steel and are available in a wide range of diameters and styles. An aftermarket exhaust will typically add horsepower/torque, lower the exhaust gas temperatures (EGT's), and can also improve engine efficiency. Exhaust systems can be offered in either 4" or 5" diameters, depending on your needs and preference. Exhaust installation is typically a DIY task that can completed right in your driveway. You can find exhaust systems from all of the leading brands like MBRP, Magnaflow, AFE, Banks Power, AP Emission Technologies, and more!
