TheP&L Motorsports Subaru WRX/STI EJ20 & EJ25 Exhaust Manifold Headeris constructed of fully T304 stainless steel schedule 10 piping and custom CNC cut T304 stainless flanges. Our unique design effectively minimizes back pressure to increase horsepower and turbo output. Incorporating a 4-into-1 merge design, this system features an equal length runner arrangement in order to help reduce the amount of exhaust gas back pressure, while still allowing for excellent sound output and tone. An equal length design was chosen due to the increased efficiency over the traditional un-equal length stock manifold. Designed, tested, and fabricated in house from start to finish, this header will increase horsepower output, when combined with accompanying ECU calibration. All P&L fabricated exhaust components come standard with our 3 year limited warranty.
