Korsh Equal Length Headers for Subaru WRX/STI/Forester/Liberty EJ

Korsh Equal Length Headers — Subaru WRX / STI / Forester / Liberty (EJ Engine)

Korsh Equal Length Headers deliver the performance upgrade your Subaru EJ engine demands. Engineered for precise fitment across WRX, STI, Forester, and Liberty models, these headers optimise exhaust flow for faster turbo spool-up, improved throttle response, and stronger power delivery across the rev range. Constructed from 304 stainless steel with cast flanges for a perfect, leak-free fit — built to handle sustained high-temperature operation in both street and track environments.
