The exhaust manifold found on the 1997-2005 Subaru Impreza 4 Cylinder Engines were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-2-1 Tri-Y 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 2.5L engine. 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><b>Package Included:</b><li>1 x Set of Header Exhaust System, Gasket(s) and Bolt(s)(ALL if any is necessary for Installation)<br><br><b>Compatible with:</b><li>Subaru Impreza RS 2.5L Non-Turbo (1997-2005)
