HKS Equal Length Header / Exhaust Manifold for 04-14 Subaru Impreza WRX STI & 15+ Subaru WRX STI (14019-AF002)
The HKS Equal Length Header (Exhaust Manifold) for the Subaru EJ25 motor works on the 04-14 Impreza WRX STI and the new 15+ WRX 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 the improved spool, providing a win-win situation. This is a great product for those looking to push the power from their OEM turbo setup or those using OEM style 2-bolt flanged pipes. This is also a great addition to lower EGT. This item includes all necessary hardware for an easy installation.
**Going from unequal to equal length will change exhaust note from rumble to a higher pitch**
