Stainless Steel Exhaust Manifold by HKS

The HKS Equal Length Header (Exhaust Manifold) for the Subaru EJ25 motor works on the 08-14 Impreza WRX/STI and the new 15+ STI. It replaces the OEM header for better flow and performance using a 4-1 setup to improve low range and high range performance (mid range is at oem level) with all things the same. Increase exhaust flow with improved spool, providing a win win situation.

This is a great product for those looking to push power from their OEM turbo setup or those using OEM style 2-bolt flanged pipes. This is also a great addition to lower EGT.

Features

  • 4-1 Exhaust Manifold (almost 4-2-1 setup)
  • Quad 42.7mm to dual to single 52mm piping
  • Increasing Low/High range power (mid range same as OEM)
  • Can be used with the oem Oil Pan
  • Made of SUH409 Steel
  • Made in Japan

Please Note: Going from unequal to equal length will change exhaust note from rumble to a higher pitch. Will not fit WRX models.

Applications

  • 2015 - 2021 Subaru WRX STI
  • 2008 - 2014 Subaru Impreza WRX STi

Perfect fit

Fit perfectly on my 13 wrx, sounds great too.

HKS Perfection

Fit perfectly on my 2007 WRX, only thing I had to change was the oil cooler, which I bypassed by running the coolant line from the block to the water pump (you'll see everything when you get in there.)

HKS headers have an awesome exhaust note along with my Invidia N1 Street. Subie rumble is still there, car overall runs so much smoother than with UELs. This should be one of the first mods anyone does to liven up the car. Low end torque is more pronounced, power band is much more linear, and the car seems to be running more efficiently overall.

Fast shipping and came in perfect condition. Currently on a stage 2 and you can feel and hear the difference. Rumble is gone when strolling around. Heat wrapped it for extra heat protection and used the heat shield and heat wrapped it as well. Would recommend this to anyone looking for a budget price headers. Upgrade the gaskets to the grimmspeed metal gaskets cause paper is no good lol but yeah it fits like a glove on my wrx with no modification

Perfect headers for budget build.

HKS Headers

These are a true 4-1 style similar to Killer Bee. Fitment was good with the slight adjustment for the O2 sensor, recommend using the heat shield it comes with and add the fiberglass pad on the top of it for increased protection. Install was very easy since the EL headers are very light! Quality is very good also no worries about cracks down the road, I personally would use GS Gaskets for the ones provided are like paper. You’ll notice after a few runs with these headers they change color mine are purple and blue(burnt titanium) so I think that looks cool! Overall score 5/5 would recommend anyone looking at EL Headers but can’t afford Killer B.
