Header layout 4-2-1
Weight 5.5kg (12.1 pound) Compared with the stock header 10.5kg, our header is 5.0kg lighter
The 4-2-1 structure [ 4(50Ǿ) – 2(50Ǿ) – 1(55-60 Ǿ taper)] increases both torque and power for all the rev ranges.
Made by light SUS304 stainless with the thickness of 1.2mm to 1.5mm, the welding, material preparation and assembly are all hand made meticulously by the experienced craftsman.
The header has a fitting hole for air/fuel ratio sensor, which comes in handy when the car is to be fine tuned.
It works great for both AP1 F20C and AP2 F22C1 to maximize the engine potential.
This special header performs very well at any driving stage.
