Killer B Motorsport 4-1 Holy Header 2-Bolt Subaru WRX 2002-2014 / STI 2004-2021 | HH-2BOLT SkylineR34_1999-2002 Whiteline performance spherical bearing endPart #: HH 2BOLT The Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine optimal design to increase power in the mid to high RPM 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
