The BD Full Bore Exhaust Manifold for the Chevy Duramax engine replaces factory driver's side pinched down unit, restoring exhaust flow and balances the V8 engine for smother running. Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes.Exhaust systems are a great way to enhance the looks, sounds, and performance of your vehicle.Exhaust headers and manifolds are designed to increase the flow of air out of your engine. An aftermarket exhaust manifold will increase horsepower by increasing air flow.The BD name became recognized in 1989, when the company introduced the first exhaust brake for the burgeoning Diesel pick-up truck market. BD's roots, however, actually date back to 1972, when Valley Fuel Injection Ltd. first opened its doors. Today, Valley Fuel Injection (now BD Diesel Truck Service & Performance Center) and BD Diesel Performance are one, with specialty divisions that focus on Diesel power train components.
