Killer B Motorsports 321 Stainless Steel Holy Header - 2002-2014 Subaru WRX / 2004-2021 Subaru WRX STI
2002-2014 Subaru WRX and 2004-2021 Subaru WRX STI 321 Stainless Steel Holy Header by Killer B Motorsports
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. 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.
- Stronger than tubing, made from 347 (321) stainless. A true high-velocity merge design is superior to fabricated tube collectors.
- The shortest possible length primaries you can have on an Equal Length header for improved transient response
- All primaries have a similar tube length and bend geometry
- Large radius bends utilize a mandrel for smooth non-restrictive flow.
- 321 is alloyed with titanium. 321 stainless steel has higher strength and toughness at elevated temperatures.
- The Holy Header Max was designed for higher flow rates with s-stepped and large diameter secondary, 2.5".
Please Note: Works with OEM EJ25 Oil Pans and Killer B Performance Aluminum Oil Pans.
