Killer Bee 321 Stainless Steel Holy Header With 2-Bolt Flange

This Holy Header uses short equal-length 4-1 primaries and a two-bolt secondary flange for pairing with a compatible up-pipe.

Why I would use it: I would use this when I want the response and high-rpm flow of the standard Holy Header design but need a conventional two-bolt connection for the rest of the turbo system.

• Thick-wall 321 stainless-steel construction
• Cast high-velocity merge collector
• Short symmetrical mandrel-bent primaries
• Two-bolt secondary outlet
• Designed for OEM-location EJ turbo installations

Fitment: 2004+ STi, 2002-2014 WRX, 2004-2013 Forester XT, 2004-2009 Outback XT, 2004-2009 Legacy GT
