Here, you are looking at the HKS Stainless Steel Equal Length Exhaust Manifold for the 2006-2014 WRX / 2004-2021 STI.

This tubular turbo exhaust manifolds offer maximum exhaust flow for increased turbo spool up & phenomenal flow capacity. Fabricated of SUH409 stainless steel.

You can have the great performance and great muffler sound of the isometric layout by changing the exhaust manifold. You will notice immediately the new exhaust sound and the gas pedal response will be much more sensitive, so it’s much easier to control.

HKS does not include an uppipe with this manifold, and these are designed to be used with a factory-style 2-bolt up-pipe. This header will fit any Turbo Subaru model that uses a triangle-style oil pan. 02-05 WRX owners will need to convert to the STI oil pan. 


  • SUH409 Stainless Steel Construction 
  • Direct Bolt-on for OEM Style Uppipes
  • Compatible with MT and AT Vehicles
  • Designed to optimize exhaust flow while increasing spool
  • Reduces Turbo Lag
  • Equal Length Design Produces a Unique Sound and Smooth Powerband
  • Gaskets Included

Fitment Notes:

2002-2005 WRX requires sti oil pan
2006-2007 WRX requires both sti oil pan and STI oil cooler

Overall really straight forward replacement to oem! I went with the hks equal length because of the benefits it has with cylinder 4 and overall power distribution. I will miss the rumble but personally the car sounds and runs more healthy now.
