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.
