<br /> <br />The exhaust manifolds found on the 1964-1979 Pontiac small block engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Long Tube off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner. Tubing has been optimized for the 5.7L(350ci), 6.6L(400ci) and 7.5L(455ci) engines. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound. <br /> <br />Specification: <li>Made of High Quality T-304 Stainless Steel with Computerized Mandrel-Bends for Strength and Durability i.e. Maximizing Smoothest High Exhaust Air Flow Rate</li> <li>TIG Welded CNC Machine Flange</li> <li>Offers the Best Flow Characteristics for the Engine at High Engine Speeds</li> <li>Increase High Flow Air, Instantly Gain 10 -15 Hp. / Tq.</li> <li>Inlet: 1 7/8&quot; OD / Outlet: 3&quot; OD / Collector Outlet: 2.5&quot; OD / 16 Gauge Wall Piping / 10mm Thick Header Flange<br /><br />Package Included:</li> <li>1 x Set of Exhaust Headers<br /><br />Fitment:</li> <li>64-70 Pontiac Tempest</li> <li>64-77 Pontiac LeMans</li> <li>64-73 Pontiac GTO</li> <li>67-79 Pontiac Firebird</li> <li>70-74 Pontiac Grand Prix</li> <li>73-75 Pontiac Grand Am</li> <li>75-77 Pontiac Grand LeMans</li> <li>Fits Round Port Engines Only</li> <li>Does not fit D-Port Models</li>
