Killer B Equal Length 4-1 Performance Holy Header W/EWG - WRX 2002-2014 / STI 2004-2014 / More

KLRB-HH-EWG

New

Killer B Motorsports

The Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine the optimal design to increase power as much as possible throughout the rev range. Primaries were made as short as possible along with a single secondary which significantly decrease header volume allowing exhaust gas pressure to build quickly.

$1,800.77

The symmetrical 4-1 design maintains high and consistent exhaust velocity as RPMs rise. You can expect significantly faster spool up time compared to long primary/double secondary designs. You will immediately notice an improvement in throttle/boost response and the ability to hold more power higher into the revs.

 

Features:

  • Provides more precise metering of boost for faster spool and increased responsiveness
  • Improved power due to reduced IWG/Turbine turbulence 
  • Up-Pipe ‘stub’ machined from solid 321 stainless for a perfect fit and thick wall reliability 
  • V-Band connection (no gaskets needed) 
  • Includes vent-to-atmosphere dump tube 
  • Designed for maximum flow using a 38mm wastegate
