    Manufacturer's Description:
    Description:
    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.

    Included:
    • Killer B Motorsport 321 Stainless Holy Header/Up-Pipe

    Features:
    • The collector is thick walled cast 347 (321) stainless.
    • Short means less header volume and quick spool up.
    • 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!
    • V-Band Up-Pipe Connection.
    • Up-Pipe included.

    Cannot believe the how much more power I got with the killer b headers invidia Catless down pipe and invidia n1 catback my buddy has the same car same year same setup but with the perrin headers and it's such a difference plus I've got 50,000 miles on them and he has only around 25,000 on his and they are cracked so everything they claim is absolute true it's the only thing I would have done different would be get the ceramic coating
