Korsh by SSI Unequal Length Headers – Subaru WRX / STI / Forester XT / Liberty GT (EJ20/EJ25)

Application: Subaru WRX 2002–2014, STI 2004–2021, Liberty GT 2005–2009, Forester XT 2004–2013 (EJ20/EJ25 turbo) Part Type: Unequal length exhaust headers with up-pipe Part Number: KOR-EXH-UEL-001

Korsh by SSI unequal length headers are built for turbocharged EJ20 and EJ25 Subarus. The unequal length layout improves exhaust scavenging over the factory manifold for sharper throttle response, quicker turbo spool and stronger delivery across the rev range – while keeping the classic Subaru boxer rumble.

Mandrel-bent, TIG-welded 304 stainless steel tubes and wax cast flanges give a leak-free fit that stands up to sustained heat on the street and on track. A slip joint allows for thermal expansion.

Why Korsh by SSI?

  • 304 Stainless Steel – Mandrel-bent, TIG-welded tubes with 2mm wall thickness.
  • Wax Cast Flanges – Precise, leak-free fitment that resists warping.
  • Unequal Length Design – Keeps the iconic boxer rumble.
  • Slip Joint – Allows for thermal expansion.
  • 2-Year Warranty – Backed by Korsh by SSI.
