This Invidia header is a direct replacement for your Subaru turbo EJ series motor's OEM header. Replacing your stock header with an aftermarket one will increase HP and decrease turbo spool-up time. This Invidia header does not ship with an uppipe. You will need to purchase one separately. It will work with any uppipe that will fit a stock manifold.
Some cars will require Subaru Oil Pan 11109AA151 for proper fitment.
Adding an aftermarket up-pipe is one of the first things you should do to your Subaru. Aftermarket up-pipes have one of the best $/HP gained ratios.

The Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine the optimal design to increase power as much as possible throughout the rev range. Primaries were made as short as possible along with a single secondary which significantly decrease header volume allowing exhaust gas pressure to build quickly.
