Proposition 65
WARNING: Handling passenger or off-highway motor vehicle parts can expose you to chemicals such as phthalates and lead, which can cause cancer and reproductive harm. To minimize exposure, service the vehicle in a well-ventilated area, wear gloves, and wash your hands.
This product is intended for off-road use only, and installation and operation are at the vehicle owner's discretion and responsibility in accordance with local state/federal laws. Click Here For More Info.
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.
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
