Upgrade your compatible Subaru WRX or WRX STI with this T304 stainless steel exhaust header and up-pipe kit, designed for 2008–2014 models equipped with EJ255 and EJ257 2.5L turbocharged engines.
Featuring a factory-style single-scroll turbo configuration, this kit combines a tubular exhaust header and up-pipe to support exhaust flow in compatible Subaru performance builds. Mandrel-bent tubing helps maintain a consistent internal diameter through bends, while CNC-machined flanges are designed for accurate alignment and reliable sealing.
Constructed from T304 stainless steel, the assembly offers heat and corrosion resistance for demanding exhaust applications. TIG-welded joints provide structural strength, and the polished finish adds a clean appearance to the engine bay.
Designed around factory-style mounting and routing for compatible applications, this kit is intended for single-scroll turbo configurations. It is not compatible with FA20 WRX models or twin-scroll turbo setups. Verify your vehicle's engine code, turbocharger configuration, and exhaust layout before ordering.
