The 04-07 Subaru STI Agency Power Equal Length Headers This header fits either the 2.0L or 2.5L engines. This header is made from 304 stainless steel and includes half inch thick flanges. The headers have a special designed collector to give perfect flow into the uppipe providing faster turbo spool and increased horsepower. The header can work with the factory uppipe or is sold with the Agency Power stainless steel uppipe. Installing this header will increase your cars horsepower and torque. Because of the equal length design, this will cause you to lose the distinct Subaru engine sound for a smoother exhaust note.
