PLM Private Label Mfg. Power Driven D-Series D16 D15 header features a true 4-1 merge collector for more equal exhaust flow. This header delivers the best peak horsepower gains while utilizing a one piece design. This is ideal for all forms of competition; Autocross, Drag racing and road racing.

Recommended for 1.6L - 1.8L engine displacements.
For the EF CIVIC Chassis, some modification to the header will be needed to fit the car and motor.
Because of different variations of oil pans on the SOHC motors, this header will need to welded to your exhaust. This header may no longer come with a 2.5 collector but just a straight cut pipe.
Stainless Steel Finish
