BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
The 6.4L Manifold set is crafted with a heavy duty 0.25 inch thick-walled Hi-Silicon ductile casting, this makes these Manifolds thicker to combat cracking due to high exhaust temperatures.
BD's exhaust Manifold set is the perfect replacement for reliability and peace of mind.
