One lesson as well (learned the hard way) wear eye protection when working with that swain coating... getting outer decorative layer flake in your eye is no fun...


It is effective though at insulating...beats wrapping headers!

Update:

The latest version of our Holy Header.

Killer B Motorsport Holy Header Max VE


The Killer B Motorsport Holy Header VE-Max was developed using state of the art CAD software, simulations, and testing, to determine optimal high power and RPM efficiency. High velocity merge collector into a stepped 2.5" secondary, the Holy Header VE-Max is for very high flow applications. Symmetrical 4-1 design maintains consistent and high velocity exhaust gas flow as RPMs rise.

Large Secondary. The Holy Header Max was designed for higher flow rates with s stepped and large diameter secondary, 2.5".

Cast Collector. Stronger than tubing, made from 347 (321) stainless. A true high velocity merge design is superior to fabricated tube collectors.

Short Equal Length Primaries. The shortest possible length primaries you can have on an Equal Length header for improved transient response.

Symmetrical Primary Design. All primaries have a similar tube length and bend geometry.

Smooth Mandrel Bends. Large radius bends utilize a mandrel for smooth non-restrictive flow.

Thick Walled 321 Stainless Steel Construction for Long Life. 321 is alloyed with titanium. 321 stainless steel has higher strength and toughness at elevated temperatures.

Made in the USA and Killer B quality! Every Header setup is inspected, assembled and pressure tested before it ships to assure a leak free setup!

Works with OEM EJ25 Oil Pans, and Killer B Motorsport Performance Aluminum Oil Pan. Fits All WRX & STi EJ Series Engines.

Curious about the merge with the uppipe. Wouldn't this larger secondary create issues when it merges with the uppipe considering pretty much all aftermarket uppipes have a 2 inch diameter (or whatever this diameter is). Will you offer a matching Uppipe eventually? Perhaps just like your regular header/uppipe combo (V-band)?

It would if you were using an OEM-ish up-pipe. Our Holy Header Max VE is intended for large rotated turbo kits, where the secondary is quite a bit larger than OEM. Generally big rotated turbo kits will use a 2.25-2.5" up-pipe, which our VE setup is based on.

For less than ~600whp, our traditional Holy Header is still what we recommend for best performance per $.

This was the line I was waiting for.

Glad I'm not stuck regretting my purchase of the traditional header. Aiming for 600WHP
