The factory OEM manifold is designed as a cost-effective component whereas, the Killer B Motorsport Performance Header is designed with the goal of Maximizing Exhaust Gas Performance and Increasing Power.

321 Stainless Steel offers benefits over common 304 Stainless Steel. 321 is made with the alloying element Titanium. This increases the material cost significantly, but for a turbocharged application, offers advantages over 304. 321 offers Increased Strength and Toughness at elevated temperatures, making it less likely to fatigue and crack. 321 was developed by the aircraft industry specifically to address longevity issues with pressurized turbocharged manifolds; addressing cracking from lower quality grades of stainless steel like 304. 321 Stainless Steel conducts less heat that 304 Stainless Steel. This means a 321 header will deliver more thermal energy to the turbocharger, improving Responsiveness and Efficiency.
