Killer Bee 321 Stainless Steel Holy Header Max VE

The Holy Header Max-VE uses the same short equal-length 4-1 architecture with a stepped 2.5-inch secondary sized for higher exhaust mass flow and rpm.

Why I would use it: I would use the Max-VE version on a high-power, high-flow EJ build where the turbo and engine need more secondary capacity than the standard Holy Header while retaining strong transient response.
