The exhaust manifolds found in the 1968-1979 Big Block Cadillac engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Tubing has been optimized for the 425, 472 and 500 engines. This creates a reduction in cylinder back-pressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
