The wait is over! Extreme Turbo Systems is proud to release our new Subaru STI V2 MaxFlow Exhaust Header for the 2004+ Subaru STI.

We designed our ETS V2 MaxFlow Header to be a direct factory replacement header. We start off with large 1 7/8 primary runners that come together in a true low angle 4-1 merge collector that then flow into a huge 2.5" secondary for maximum scavenging and exhaust flow.

Features

  • 1 7/8" primary runners with 2 1/2" secondary for maximum flow.
  • CNC mandrel bent runners.
  • Custom .100 USA made thick wall tubing for durability.
  • Low angle 4-1 merge collector for maximum flow and exhaust scavenging.
  • Slip fit connection for ease of removal and installation.
  • 2-Bolt , 3-Bolt, or V-band up pipe flange options.
  • Stock replacement design.
  • Low profile design for maximum clearance. 
  • Confirmed Fitment with XL Oil Pans like IAG and KillerB
  • Surfaced flanges for a leak free seal.
  • 304 Stainless steel construction.
  • 100% built in house and made in the USA.

Really nice piece

I was in the market for a updated header to replace my swain coated gtspec uel from 2005. Definitely glad I went with this ETS v2 maxflow. Big tube primaries with some beefy flanges. Overall construction is top notch. 👌 5 stars all day

Ets max flow headers

I had killer b headers on before pushing 600 hp but when I told my tuner I’m looking for 800 plus he said let’s swap ur headers out and upgrade some fuel stuff I’m waiting for tune date to see what these upgrades lay out.

Best subaru header you will ever need.

Looks and feels very well build with heavy duty materials, the vband up pipe set up is amazing and easy to connect. Shout out to everyone at extreme turbo systems!

As usual ETS crushes with their product. We’re expecting to make additional WHP on less PSI with these headers…and the quality is far superior to any other. Look no further than these headers
