Features & Product Details

RallySport Direct is proud to bring you quality craftsmanship brought to you by Killer B Motorsport. Killer B are pure artists in metal fabrication, and they have a large catalog with a wide variety of performance enhancing, oiling, fabrication components, along with accessories for your interior, exterior, or your engine bay.

Here you are looking at 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. This header is a great option for those of you looking to improve the sound and power throughout the entire RPM range.

Note that this header will come provided with a v-banded up-pipe.

Here are some key features:

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 keeps 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 for Long Life: 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.

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

Q: 2011 wrx Jschwartz3 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 Izzy3 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.
- 0 of 0 people found the following answer helpful
  A: No. 2006 STi does not have an OEM EGT, only the O2 sensor in the manifold. We do include the bung for that.
