MAP 2015+ Surbaru WRX FA20 Twin Scroll Equal Length Header

Since the great success of our Subaru EJ25 header we have been asked over and over when we would do the same for the 2015+ WRX FA20DIT, and the time has finally come!

Made from our standard 304 Stainless, and hand TIG welded in our facility we bring to you a simple to install and highly benifical modification to those of you modifying your cars to make more power! Designed to utilize single piece free flowing mandrel bent runners, along with our 304 Stainless Billet CNC merge collector and turbo flange.

With all of that we have a much higher flowing header that will offer not only improved turbo response, but also higher peak power availability in comparison to the restrictive stamped OEM header.


  • Made In The USA
  • Hand TIG welded in our Cottage Grove, MN Facility
  • 1/2 inch thick stainless flanges to prevent warping
  • Crafted from 304 USA-Made stainless steel
  • Flat sanded flanges to ensure a leak free design


  • Reduce Turbo lag
  • Quality that will last the life of the car
  • Larger, free flowing header capable of more power output
  • Simple Install with standard hand tools


  • Subaru FA20DIT, FA20F
  • 2015 - 2021 Subaru WRX
  • 2014 - 2018 Subaru Forester XT

What's In The Box?

  • 1 - Twin Scroll Equal Length Header
  • 10 - M10x1.25 Flanged Nuts
  • 3 - Grimmspeed Gaskets (Optional)



  • MAP Limited Lifetime Warranty

Sounds amazing

I love these headers. Had to replace my OEM exhaust manifold because it kept failing. Recall fix still had issues with the nut coming loose and falling off. These headers with the gaskets have been rock solid. The vibration on start up is a nice bonus.

Seems solid (Grimmspeed header)

I’m replacing a massively cracked Perrin header with this Grimmspeed header. I really like how the collector at the turbo flange is robust and cast (where my Perrin cracked). The flanges are really thick and the piping appears thicker too. To use the stock heat shield that covers the hot side of the turbo, I had to trim it way back due to its design, including the small bracket it connects to. So it’s not %100 plug and play in that respect. I’m really happy with my purchase and a huge shout out to customer service at MAPerformance. They quickly helped resolve a stocking issue and my header literally arrived the following day.

Amazing part awesome customer service. Just like with any other Fa header it can be a pain to get on but if you take your time it goes right on. Great welds and fast shipping.
