Quick Overview

NOT CARB LEGAL, RACE or TRACK ONLY

Description:
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.

Features:
- Improved throttle and Boost Response
- Customers report +25wtq and +25whp on average
- More Consistent EGTs across all cylinders
- More Power Higher into the Rev range
- Improved Fuel Efficiency
- Perfect fit! (some WRX models may require OEM Oil Cooler to be rotated)
