Description
Take your 7.3L Powerstroke to the next level with the DIESELR Stainless Steel Header Manifolds — built tough, built to last, and built to let your truck breathe like it should’ve from the factory. Designed to replace those crack-prone stock manifolds, this kit brings serious durability and flow to the table for your F250, F350, or F450.
Made from high-grade stainless steel, these manifolds resist warping, cracking, and corrosion — even under the heat and stress of towing, hauling, or full-send driving. Whether you’re working the truck hard or dialing in a performance setup, these headers are up for the job.
The manifolds have been re-engineered and reinforced in all the weak points where OEMs typically fail. No more dealing with leaks or performance loss from thermal stress. Plus, every unit undergoes a rigorous inspection process to ensure top-notch quality from Doctor Diesel USA.
NOTE:
These headers do not come with an exhaust back pressure sensor bung. Depending on your turbo setup, tuning or modification may be required.
