The Killer B equal length exhaust header is a great performance upgrade for your EJ series engine and we have this header fitted on both our hillclimb car and STI hatchback. We have the following header options for sale:
- Exhaust header with a standard fitment up-pipe (fitment 2004+ STi, 2002-2014 WRX, 2004-2013 Forester XT, 2004-2009 Outback XT, 2004-2009 Legacy GT)
- Exhaust header with a two bolt flange
- "Max VE" exhaust header - for high horsepower applications
Each header can be specified with exhaust gas temperature senor bungs on either cylinder #4 or on all cylinders if desired. A Swaintech multi-layer ceramic coating (as used on our hillclimb car's header) can also be applied on the header which requires a 8 week lead time.
The Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine optimal design to increase power as much as possible throughout the rev range. Short as possible primaries with a single secondary decrease header volume significantly, allowing exhaust gas pressure to quickly build. Symmetrical 4-1 design maintains high and consistent exhaust velocity as RPMs rise. You can expect faster spool up time compared to long primary/double secondary designs. A difference that you will immediately notice in throttle/boost response and the ability to hold more power higher into the revs.
