AFE BladeRunner Exhaust Manifold Ductile Iron 11-14 Ford 6.7L Powerstroke

Are you looking to improve exhaust flow and reliability? The aFe BladeRunner Exhaust Manifold is built from heavy-duty ductile iron for maximum strength in high-heat, high-boost diesel applications. Designed to replace the factory manifold, this upgraded casting helps reduce common issues found in OEM units, such as cracking, warping, and restricted exhaust flow caused by thin-wall construction and uneven runner design. The internal runner layout is engineered to improve exhaust gas velocity and balance flow to the turbocharger, supporting faster spool-up and more consistent boost response under load.

Built for work trucks and performance setups, the BladeRunner manifold also focuses on long-term thermal stability by reinforcing high-stress areas and improving resistance to extreme heat cycling. Precision-machined mounting surfaces ensure a proper gasket seal, while the robust one-piece construction eliminates weak points found in factory designs. The result is a stronger, more efficient exhaust manifold built to support towing, tuning, and heavy-duty use while improving overall engine efficiency and turbo performance.
