Product Description

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 compared to long primary/double secondary designs. A difference you will immediately notice in throttle response and the ability to hold more power higher into the revs.

 

Features include:

Short Equal Length Primaries. quick

  • All primaries have a similar tube length AND
  • 321 is alloyed with titanium, costs more, a lot more, but it’s the ideal

  • Weights only 17 pounds
  • Works with OEM EJ25 Oil Pans, and Killer B Motorsport Performance Aluminum Oil Pan!
