BD Exhaust Manifold

The 6.7 Cummins BD-Power Exhaust Manifold is a must have manifold upgrade. Cast from high-silicon ductile iron this heavy-duty, multi-piece exhaust manifold has built-in expansion joints that allow for growth when heated rather than cracking like the stock application. Additional material in the turbo mount area as well as webbing between ports is also added for increased strength. Exhaust manifold gaskets sold separately
