Killer B (EJ Series) Equal Length 4-1 Holy Header

Killer B

$1,656.00 
KB-KLBHH4-1



Item Description: 

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 significantly decrease header volume allowing exhaust gas pressure to build quickly. The 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 you will immediately notice in throttle/boost response and the ability to hold more power higher into the revs.

  • Cast Collector. The collector is thick walled cast 347 (321) stainless.
  • Short Equal Length Primaries.
  • Smooth Mandrel Bends.
  • Thick Walled 321 Stainless Steel Construction for Long Life.
  • High Heat Retention.
