Here you are looking at the Killer B Motorsport 321 Stainless Steel Holy Header DIY Rotated. This header is available for those converting to the rotated turbo setup, and want a premium exhaust manifold to make the power and the performance. This will come with a universal-style rotated pipe that will come with a weld-on V-band flange for one end, and the other end will be open to allow the user to fabricate that end to suit the turbocharger of their choice. This exhaust manifold has been designed for those who want to make a substantial amount of power that can be associated with a rotated setup, and it is capable to provide the flow needed that would otherwise be limited by the factory exhaust manifold or other manifold designs. 

 

 

DETAILS:

  • SHORT EQUAL LENGTH PRIMARIES: The shortest possible length primaries you can have on an Equal Length header - Short means less header volume and quick spool up
  • SYMMETRICAL PRIMARY DESIGN: All primaries have a similar tube length AND bend geometry - This keeps the pulse velocities high and consistent compared to equal length headers with different (non-symmetrical) primary tubing geometry
  • SMOOTH MANDREL BENDS: All of the bends utilize a mandrel for smooth non-restrictive flow - Not only that, they use the largest bends possible at every location - It would be cheaper to use 2” bends everywhere, like others do, but that’s not going to give the best performance
  • THICK-WALLED 321 STAINLESS STEEL CONSTRUCTION: 321 is alloyed with titanium, costs more, a lot more, but it’s the ideal material for high-temperature turbocharged applications
  • HIGH HEAT RETENTION: 321 stainless steel conducts less heat than 304 stainless steel - The short primaries and properly sized secondary’s also pull less heat from the exhaust gasses increasing turbine efficiency - Large tubing headers expose the exhaust gasses to more surface area transmitting more heat and reducing exhaust energy - You can also ceramic coat or wrap the headers (and keep the warranty) without exceeding the temperature range like you can with 304 stainless.
  • Up-Pipe to Manifold V-Band Included (not welded)
  • Includes Non-Trimmed or Welded 321 Stainless Steel Up-Pipe
  • No Turbo Flange Provided
  • Works with OEM EJ25 Oil Pans, and Killer B Motorsport Performance Aluminum Oil Pan
  • No Accommodations for External WasteGate Included
