Killer B Equal Length 4-1 Holy Header EJ Series

Description

Part #: klbHH4-1

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.
