The header for DC5 was totally redesigned and has been released as a FX Pro series.
In order to maximize the K20A potential, each pipe length and merging shape are reexamined from the scratch for achieving further gain in torque and power. The header generates an excellent engine response and acceleration in all rev ranges.
Each header is 100 % beautifully handmade with amazing details by professional craftsmen who have a thorough knowledge of header.. This header is a real beauty and you can feel the difference.
