Evo: Stock Replacement


Form always follows function in everything we create and although we initially ignored the “look” of this piece to allow it to emerge as we followed our strict requirements, it produced something beautiful.

The design and execution was really scrutinized to be sure that it was a replacement worthy of its job because the stock exhaust manifold is a very stout performing piece already.

Check out our back-to-back dyno test of this piece and and FP Race Manifold!


Out of stock



  • Exact factory placement.
  • Near equal length runners.
  • Uses the ideal runner size to aid in quick spool, transient response, and aggressive midrange.
  • Merge collector that mimics the turbine housing angle of entry, giving each runner a direct shot at the turbine wheel.
  • Increased VE and power/airflow per psi, particularly with upgraded camshafts where the overlap can be taken advantage of for scavenging.
  • Perfectly matched for both MHI and FP bolt-on turbine housings.
  • No tight radius or cheated/compromised bends.
  • 321 Stainless, 100% fully backpurged.
