Killer B Motorsport 4-1 Max VE Holy Header Exhaust Manifold 2 Bolt w/ Up-Pipe 2002-2014 WRX / 2004-2021 STI / 2004-2013 Forester XT / 2004-2009 Outback XT / 2004-2009 Legacy GT
Engineered for high-flow, high-RPM performance, the Killer B Holy Header VE-Max was developed using advanced CAD, simulations, and rigorous testing to optimize exhaust efficiency. Designed for serious enthusiasts, this header delivers exceptional power and throttle response.
Features:
- Large Secondary (2.5") – Stepped and oversized for very high-flow applications, maximizing exhaust evacuation.
- Cast Collector – Crafted from 321 stainless steel (alloyed with titanium) for superior strength, durability, and high-velocity merge performance.
- Short Equal-Length Primaries – Shortest possible equal-length primaries improve transient throttle response.
- Symmetrical Primary Design – All primaries feature similar tube lengths and bends for consistent exhaust flow.
- Smooth Mandrel Bends – Large-radius bends ensure non-restrictive, high-velocity flow.
- Thick-Walled 321 Stainless Steel Construction – Handles extreme temperatures while providing long-term durability.
- Made in the USA – Every header is inspected, assembled, and pressure-tested to guarantee a leak-free setup.
Compatibility:
- Works with OEM EJ25 oil pans and Killer B Performance Aluminum Oil Pan
- Fits all WRX and STi EJ series engines
Notes:
- Killer B does not warranty headers that have been wrapped.
- Upipe is for representation purposes only, will ship with a 2 bolt up pipe.
