Killer B Equal Length 4-1 Holy Header EJ Series 2-Bolt Wire In ECU's Large variety of Analog inputThe Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine the optimal design for increasing 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
