These heavy-duty exhaust manifolds for 2015–2019 Ford 6.7L Powerstroke are crafted with 0.275-inch thick-walled hi-silicon ductile casting, 75% thicker than factory manifolds, and engineered with optimized exhaust port sizes to maximize exhaust flow. These manifolds address one of the Ford 6.7L's common failure points. Built to eliminate cracking, leaks, and warping caused by high exhaust temperatures, they deliver proven turbo response and durability for work trucks, towing, hauling, and daily driving.

Fitment

• 2015–2016 Ford 6.7L Powerstroke — F-250, F-350 (pickup)
• 2017–2019 Ford 6.7L Powerstroke — F-250, F-350 (pickup); F-350, F-450, F-550 (cab/chassis)

Product Details

• Material: Hi-silicon ductile cast iron with 0.275-inch thick walls
• Flow Optimization: Computational fluid dynamics were used to optimize flow and exhaust port sizes have been increased to match gaskets
• Performance Gain: Average flow increase of approximately 8.1% per port versus OEM (OEM approximately 169 CFM per port versus aftermarket approximately 174 CFM per port)
• Thermal Durability: Longer exhaust studs and spacers plus thicker, more durable machined bolting flanges
• Heat Protection: POR15 black high-temperature coating helps the manifold resist corrosion over time
• Kit Includes: Left and right exhaust manifolds, longest stud and spacer kit, manifold gaskets, crossover tube gasket, EGR port gasket, and M8 stud install tool
• Emissions Compliance: Fully EGR compatible
• Weight: 40.0 lbs

Installation

Installation requires approximately 9 hours and demands careful removal of shields, CAC plumbing, and related lines. Professional installation is recommended to ensure proper stud torque sequencing and gasket sealing.

Check local emissions regulations before purchase. Professional installation is recommended.
