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 Steel Holy Header With 2-Bolt Flange SwainTech Multi-Layer Ceramic Coating (additional 8 weeks) 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! |
