This kit is the driver's side manifold only. For both driver's side and passenger side (2011-2014 Powerstrokes), use P/N# BD1043007.
BD focused on solving one of the Ford 6.7L common failures, the exhaust manifolds.
The BD Mighty Manifold is crafted with a heavy duty 0.275” thick-walled Hi-Silicon ductile casting - making it 75% thicker than OEM. This helps to combat manifold cracking due to high exhaust temperatures and long cycle life.
Longer exhaust studs and spacers plus thicker, more durable machined thicker bolting flange improves thermal durability. Flow simulation and gasket matched ports have improved flow over the OEM manifold.
Fully EGR compatible, BD's exhaust manifold set is the perfect replacement for reliability, performance and ease of mind.
