Invidia 05-12 WRX/STi Equal Length Racing Manifold Header (02-05 Need STi Oil Pan)
This type of manifold is ideal for those of you looking to surpass large horsepower figures that would otherwise be limited by the flow capacity of the factory exhaust manifold. When shooting for 600+ horsepower and beyond, this manifold can accommodate these numbers as it has been designed with a 2-bolt up-pipe flange for those of you who are upgrading to an external-style up-pipe, or it may accommodate some rotated turbo setups. Another great feature is the smooth bends as the manifold design will allow for an unobstructed flow path for the exhaust to exhale the exhaust gases as proficiently as possible for those with moderate bolt-ons.
