Killer B Motorsports

The Killer B Motorsport Holy Header was developed using state of the art CAD software & simulations to determine the optimal design to increase power as much as possible throughout the rev range. Primaries were made as short as possible along with a single secondary which significantly decrease header volume allowing exhaust gas pressure to build quickly.

More details

$1,256.00

The symmetrical 4-1 design maintains high and consistent exhaust velocity as RPMs rise. You can expect significantly faster spool up time compared to long primary/double secondary designs. You will immediately notice an improvement in throttle/boost response and the ability to hold more power higher into the revs.

Features:

  • Works with any 2-bolt up-pipe, including rotated setup
  • Two bolts mean reduced cost
Up-pipe not included
