BD Diesel Manifold Exhaust – 2001-2010 Duramax Best Price

You may not know it, but the factory drivers side exhaust manifold is pinched down to allow for steering shaft clearance, which actually is not required. As a result, thismanifold only flows 80-percent of the passenger side. BDs Full Bore exhaust manifoldrestores exhaust flow balance, improving power and reducing EGT. 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.\\u003cbr\\u003e\\u003ca href=\\
