Finish
  • Add MORE RUMBLE to your FA20 turbocharged Subaru! Sure, twin scroll manifolds are good for power and quick turbo spool, but they DO NOT RUMBLE! What good is a Subaru with no rumble? You want power? You want spool? Look elsewhere. You want rumble? This is your header.

    Looking for dyno results for this header? Too bad. Just assume your turbo will spool slower and your peak power will be less. (In its defense, the tubing runs of this manifold are very short, which should somewhat offset the loss of the equal-length design.)

    Do you want faster spool? Of course you don't, which is good, because this header is not made for that. You are HERE FOR THE RUMBLE.

    In the words of Killer B Motorsport themselves: " It burbles like Satan farting in the bathtub. "

    Even thought this part goes against everything we stand for, we're not going to skimp on quality. You still get:

    321 Stainless Steel offers benefits over common 304 Stainless Steel. 321 offers increased strength and toughness at elevated temperatures, making it less likely to fatigue and crack. 

    Cast collectors Maximize flow potential and highest reliability.

    Quality and Craftsmanship ½” Thick billet precision CNC machined flanges for exceptional durability and ground flat for leak-free service. TIG welded to aircraft quality standards and ground smooth to assure smooth turbulent-free gas flow. 

    Made in the USA. Every raw material used from start to finish; molten metal to finished product, is certified to have been made in the USA. Limited Lifetime Warranty.

    Choose standard uncoated finish, or Swain coated which is a super-robust heat deflection coating to help reduce temperatures for better performance. Note: Allow as much as two months lead time for Swain coating.

    Manifold hardware, header gaskets, and turbo gasket are sold separately.

    Fits all 2015-2021 Subaru WRX.
