2004-2009 Subaru Legacy Killer B EL 4-1 Holy Header w/ EWG
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.
Provides More Precise Metering of Boost for Faster Spool and Responsiveness
Improved Power Due to reduced IWG/Turbine Turbulence
Up-Pipe ‘Stub’ Machined from Solid 321 Stainless Bar for a Perfect Fit and Thick Wall Reliability
