Borla 02-14 WRX / 04-18 STi Header

This Borla header is built from T-304 austenitic stainless steel, which is a strong material that resists corrosion better than T-400 series stainless steel. It's designed to improve exhaust flow, which can lead to more power and torque. The header includes a unique, stiffened flex joint to handle engine movement and vibration. It also features ultra-smooth mandrel bends to ensure the exhaust gases can move freely, maximizing power output. This header is manufactured in the USA and comes with a Million-Mile Warranty from Borla.

Included with this header are the header itself, a collector/muffler, pan-e-vac tubes, and stainless steel Stage 8 self-locking bolts. Please note that gaskets are not included; you'll need to reuse your original equipment gaskets or purchase new ones separately. The precision CNC manufacturing ensures it fits accurately on your vehicle. This header has California Air Resources Board Executive Order (E.O.) # D-276-12 for the 2001-2003 Subaru Impreza WRX, meaning it meets emissions standards for those specific models.
