The Spoon 4-2-1 header is designed to provide the maximum balance between peak power and torque.

To develop this header, Spoon tested all possible combinations of pipe diameter, length, bends, and rotation through engine dyno, flow bench, and driving/circuit tests. The result was an extremely lightweight header (6.8kg) with substantial peak and mid-range power gains. Weight saving 50% over the OEM manifold of 11.5

For best results we recommend installing the with Spoon N1 Muffler and B-pipe.
