The Killer B Motorsport Holy Header VE-Max was developed using state of the art CAD software, simulations, and testing, to determine optimal high power and RPM efficiency. I High velocity merge collector into a stepped 2.5" secondary, the Holy Header VE-Max is for very high flow applications. Symmetrical 4-1 design maintains consistent and high velocity exhaust gas flow as RPMs rise.
- 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.
