The HKS Equal Length Header (Exhaust Manifold) for the Subaru EJ25 motor works on the 08-14 Impreza WRX/STI and the new 15+ STI. It replaces the OEM header for better flow and performance using a 4-1 setup to improve low range and high range performance (mid range is at oem level) with all things the same. Increase exhaust flow with improved spool, providing a win win situation.
This is a great product for those looking to push power from their OEM turbo setup or those using OEM style 2-bolt flanged pipes. This is also a great addition to lower EGT.
Please Note: Going from unequal to equal length will change exhaust note from rumble to a higher pitch. Will not fit WRX models.
