MFG: HH-2BOLT-EGT

 

This is the Killer B Motorsport 321 Stainless Steel Holy Header. This particular header will come with the 2-bolt up pipe option, and it will also come equipped with an EGT sensor bung on the number 4 cylinder pipe. This header is a great option for those of you looking to improve the sound and power throughout the entire RPM range. 

 

 

 

HIGHLIGHTS:

 

  • CAST COLLECTOR: The collector is made of thick-walled cast 347 stainless - This design removes several welds which removes flow disruption for less turbulence - This also allows the collector to be designed as a true high-velocity merge
  • SHORT LENGTH EQUAL PRIMARIES: Shorter length primaries make for an equal length header which means less header volume and quick spool up
  • SYMMETRICAL PRIMARY DESIGN: A similar tube length and bend geometry will keep the pulse velocities high and consistent when compared to equal length headers with different non-symmetrical primary tubing geometry
  • SMOOTH MANDREL BENDS: All the bends utilize a mandrel to promote non-restrictive flow, and Killer B uses the largest bends possible at every location
  • THICK-WALLED 321 STAINLESS STEEL CONSTRUCTION: 321 is alloyed with titanium which not only costs more but it is ideal to handle the elements of extreme heat found in the turbocharger - With that being said, the turbocharger will create heat that will surpass the limits of 304 stainless steel, and 321 is more robust to promote longer life
