Killer B Motorsports Holy Header Max


Highlights

  • Large Secondary. The Holy Header Max was designed for higher flow rates with s stepped and large diameter secondary, 2.5".
  • Cast Collector. Stronger than tubing, made from 347 (321) stainless. A true high velocity merge design is superior to fabricated tube collectors.
  • Short Equal Length Primaries. The shortest possible length primaries you can have on an Equal Length header for improved transient response.
  • Symmetrical Primary Design. All primaries have a similar tube length and bend geometry.
  • Smooth Mandrel Bends. Large radius bends utilize a mandrel for smooth non-restrictive flow.
  • Thick Walled 321 Stainless Steel Construction for Long Life. 321 is alloyed with titanium. 321 stainless steel has higher strength and toughness at elevated temperatures.
  • Made in the USA and Killer B quality! Every Header setup is inspected, assembled and pressure tested before it ships to assure a leak free setup!
  • Works with OEM EJ25 Oil Pans, and Killer B Motorsport Performance Aluminum Oil Pan. Fits All WRX & STi EJ Series Engines.
  • We do not warranty wrapped headers.
