For those looking to squeeze additional power from their 08+ Subaru WRX STi, the equal length header is the ultimate solution. By utilizing equal exhaust runners, a smoother exhaust flow is created, which will yield additional horsepower. Unfortunately, as a byproduct, the "boxer rumble" is lost from your exhaust tone.
This equal length header can also fit the standard WRX models when combined with the STI oil pan for appropriate clearance.
