The Tomei Expreme exhaust manifold for the Subaru WRX improves the exhaust performance by improved design and increased efficiency. The result is a unique sounding exhaust with improved response and power designed for the EJ20 engine.


  • High efficiency 4-1 design for improved power and response
  • Tomei developed un-equal length for improved turbo performance
  • Increased pipe diameter to 60mm over standard 42.7mm for greater flow
  • Unequal length retains the unique boxer sound

Kit includes

  • Exhaust Manifold
  • Bolts, gaskets and header wrap
  • Instruction Manual and sticker note: From our experience this 4-1 header design makes the MOST power of any header design on the market for the Subaru including the equal length 4-2-1 design. We have seen up to a 15whp peek gains over the Cusco and Perrin equal length headers.
