Features & Product Details

RallySport Direct proudly carries an excellent collection of quality upgrades brought to you by the metal artists at Killer B Motorsport. 

 

Here you are looking at the Killer B Motorsport 321 Stainless Steel Holy Header. This particular header will come with the v-band up pipe option, and it will also come equipped with an EGT sensor bung. 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 EQUAL LENGTH 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 - The turbocharger will create heat that will surpass the limits of 304 stainless steel, and 321 is more robust to promote longer life 
  • V-BAND UP-PIPE W/EGT BUNG: This up-pipe has been designed to easily attach and adjust to the exhaust manifold through a v-band flange, and it will have a factory or factory-like turbo flange on the other end 
  • Optimizes the exhaust flow throughout the entire RPM range
  • Improves horsepower and torque
  • Reduces the turbo lag
  • Produces an aggressive exhaust note
  •  

     

    NOTES:

  • May not fit some Forester, Outback, and Legacy models with the OEM oil pan and cooler.

    QUESTIONS & ANSWERS

    • Q: Moroso steel oil pan fitment  aryole628703 years ago

      Is there any place i can find whether these headers fit the steel moroso oil pan
    • Q: 2011 wrx  Jschwartz4 years ago

      Will I be fine with a stage 2 ots cobb tune running this header
      • 0 of 0 people found the following answer helpful

        A:  I would recommend avoiding heavy or wide open throttle until you can get pro-tuned. The header improves the efficiency of the engine/turbocharger. Having the car tuned to take advantage of the optimized flow will not only allow for even more power, but also assure all ECU parameters are within safe limits.

    • Q: Killer B Up Pipe  Izzy5 years ago

      Does the up pipe comes with an EGT bung too? I am not sure if my current 2006 sti stock up pipe has EGT.
