321 Stainless Holy Header W/EWG by Killer B Motorsport
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
- Cast Collector
- Short Equal Length Primaries
- Symmetrical Primary Design
- Smooth Mandrel Bends
- Thick Walled 321 Stainless Steel Construction for Long Life
- High Heat Retention
- Made in the USA and Killer B quality!
Applications
- 2002-2014 Subaru WRX
- 2004-2020 Subaru WRX STI
What's In The Box?
- Header w/ EWG
Warranty
- Manufacturer Standard Warranty (will not honor warranty on wrapped headers)
