Innovated first by Pleasure craft Marine, the center pyramidal Exhaust Manifold is now an industry standard. Its unique design allows the hot exhaust gases to naturally flow up the reversible riser where it is then directed to the exhaust outlets. This compact, free breathing design allows for installation at all standard angles without modification and prevents excessive back pressures. Available in high gloss black cast iron, ready to run!
