Few things add better looks, better sound, and better performance to your 7.3L in one bolt-on package. Sinister Diesel’s Powerstroke 7.3L Stainless Exhaust Kit is designed to maximize your Super Duty’s horsepower and deliver more torque to the wheels. Each exhaust kit is precision cut and bent from 409 stainless steel for high corrosion resistance and easily bolts together using the included hardware and gaskets. With the reduced restriction and improved exhaust flow from the four-inch diameter stainless pipe, horsepower and torque is improved due to quicker turbo spool-up, and you’ll see lower exhaust gas temperatures too, due to lower backpressure.

This full 4-inch 7.3 Powerstroke diesel exhaust kit comes with all the components that you need to install a full stainless exhaust and muffler for any cab and bed size configuration including an 18-inch muffler, a  muffler replacement, and a polished stainless steel exhaust tip with a rolled edge and proudly stamped with the Sinister Diesel logo.
