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.
