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.
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.
