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.

Have to say I like the look of this header. Wrapped it with some heat wrap. Helps give good sound and performance. Happy with the purchase.
I have these on my build, paired with the Boostlab 58xr, with all my other mods and fuel upgrades, I was very very pleased with the sound and the power I was making along side it.
However, after about 3500-4000 miles I discovered quite a big exhaust leak from the turbo to header flange. I thought it was the gasket failure since it was all wobbly.Any boost above 20psi and it was whistling pretty loud. Thought it was my issue during tightening sequence or didn’t position them exactly right, turns out the flange warped after enough heat cycles. Having to have it milled down at a machine shop after buying new gaskets that also didn’t fix my issue. Could be an isolated incident but sort of discouraging if I’m going to have to do this again. Hopefully not. Great sound, and power was there for a little bit.
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.
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.
This is the best bang for your buck. You won't regret it.
