| 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 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! |
